    11691100 Since ADOdb 2.42, you can pass a  table name instead of a recordset into  
    11701101GetInsertSQL (in $rs), and it will generate an insert statement for that table.

    13641207The old way of doing transactions required you to use

    1367 $ok = $conn->Execute($sql);

    13721209This is very complicated for large projects because you have to track the error  
    13731210status. Smart Transactions is much simpler. You start a smart transaction by calling  
    13741211StartTrans():

    13811213CompleteTrans() detects when an SQL error occurs, and will Rollback/Commit as  
    13821214appropriate. To specificly force a rollback even if no error occured, use FailTrans().  
    13831215Note that the rollback is done in CompleteTrans(), and not in FailTrans().

     1935<p>The $where clause is required if $mode == 'UPDATE'. If $forceUpdate=false then we will query the

     1995<font>  </font></p><p><font> To understand why StartTrans() is superior to BeginTrans(),  
    22781996  let us examine a few ways of using BeginTrans(). 
    22791997  The following is the wrong way to use transactions:  
    2280 <pre> 
    2281 $DB->BeginTrans(); 
    2282 $DB->Execute("update table1 set val=$val1 where id=$id"); 
    2283 $DB->Execute("update table2 set val=$val2 where id=$id"); 
    2284 $DB->CommitTrans(); 
    2285 </pre> 
    2286 <p>because you perform no error checking. It is possible to update table1 and  
     1998</font></p><pre><font>$DB-&gt;BeginTrans();<br>$DB-&gt;Execute("update table1 set val=$val1 where id=$id");<br>$DB-&gt;Execute("update table2 set val=$val2 where id=$id");<br>$DB-&gt;CommitTrans();<br></font></pre> 
     1999<p><font>because you perform no error checking. It is possible to update table1 and  
    22872000  for the update on table2 to fail. Here is a better way:  
    2288 <pre> 
    2289 $DB->BeginTrans(); 
    2290 $ok = $DB->Execute("update table1 set val=$val1 where id=$id"); 
    2291 if ($ok) $ok = $DB->Execute("update table2 set val=$val2 where id=$id"); 
    2292 if ($ok) $DB->CommitTrans(); 
    2293 else $DB->RollbackTrans(); 
    2294 </pre> 
    2295 <p>Another way is (since ADOdb 2.0):  
    2296 <pre> 
    2297 $DB->BeginTrans(); 
    2298 $ok = $DB->Execute("update table1 set val=$val1 where id=$id"); 
    2299 if ($ok) $ok = $DB->Execute("update table2 set val=$val2 where id=$id"); 
    2300 $DB->CommitTrans($ok); 
    2301 </pre> 
    2302 <p> Now it is a headache monitoring $ok all over the place. StartTrans() is an

     2004<p><font> Now it is a headache monitoring $ok all over the place. StartTrans() is an 
    23032005improvement because it monitors all SQL errors for you. This is particularly 
    23042006useful if you are calling black-box functions in which SQL queries might be executed. 
    23052007 Also all BeginTrans, CommitTrans and RollbackTrans calls inside a StartTrans block  
    23062008  will be disabled, so even if the black box function does a commit, it will be ignored.

    3207 <h1>Database Driver Guide<a name="driverguide"></a></h1> 
    3208 <p>This describes how to create a class to connect to a new database. To ensure  
    3209   there is no duplication of work, kindly email me at jlim#natsoft.com.my if you  
    3210   decide to create such a class.</p> 
    3211 <p>First decide on a name in lower case to call the database type. Let's say we  
    3212   call it xbase. </p> 
    3213 <p>Then we need to create two classes ADODB_xbase and ADORecordSet_xbase in the  
    3214   file adodb-xbase.inc.php.</p> 
    3215 <p>The simplest form of database driver is an adaptation of an existing ODBC driver.  
    3216   Then we just need to create the class <i>ADODB_xbase extends ADODB_odbc</i>  
    3217   to support the new <b>date</b> and <b>timestamp</b> formats, the <b>concatenation</b>  
    3218   operator used, <b>true</b> and <b>false</b>. For the<i> ADORecordSet_xbase extends  
    3219   ADORecordSet_odbc </i>we need to change the <b>MetaType</b> function. See<b>  
    3220   adodb-vfp.inc.php</b> as an example.</p> 
    3221 <p>More complicated is a totally new database driver that connects to a new PHP  
    3222   extension. Then you will need to implement several functions. Fortunately, you  
    3223   do not have to modify most of the complex code. You only need to override a  
    3224   few stub functions. See <b>adodb-mysql.inc.php</b> for example.</p> 
    3225 <p>The default date format of ADOdb internally is YYYY-MM-DD (Ansi-92). All dates  
    3226   should be converted to that format when passing to an ADOdb date function. See  
    3227   Oracle for an example how we use ALTER SESSION to change the default date format  
    3228   in _pconnect _connect.</p> 
    3229 <p><b>ADOConnection Functions to Override</b></p>

     2956 
     2957Adodb-dict contributions by Gaetano: 
     2958<br> 
     2959+ Support for INDEX in data-dict. Example: 
     2960idx_ev1. The ability to define indexes using the INDEX keyword was added in ADOdb 4.94. The following example features mutiple indexes, including a compound index idx_ev1.  
     2961<pre> 
     2962  event_id I(11) NOTNULL AUTOINCREMENT PRIMARY, 
     2963  event_type I(4) NOTNULL  <b>INDEX idx_evt</b>, 
     2964  event_start_date T DEFAULT NULL <b>INDEX id_esd</b>, 
     2965  event_end_date T DEFAULT '0000-00-00 00:00:00' <b>INDEX id_eted</b>, 
     2966  event_parent I(11) UNSIGNED NOTNULL DEFAULT 0 <b>INDEX id_evp</b>, 
     2967  event_owner I(11) DEFAULT 0 <b>INDEX idx_ev1</b>, 
     2968  event_project I(11) DEFAULT 0 <b>INDEX idx_ev1</b>, 
     2969  event_times_recuring I(11) UNSIGNED NOTNULL DEFAULT 0, 
     2970  event_icon C(20) DEFAULT 'obj/event', 
     2971  event_description X 
     2972</pre> 
     2973<br> 
     2974+ Prevents the generated SQL from including double drop-sequence statements for REPLACE case of tables with autoincrement columns (on those dbs that emulate it via sequences) 
     2975<br> 
     2976+ makes any date defined as DEFAULT value for D and T columns work cross-database, not just the "sysdate" value (as long as it is specified using adodb standard format). See above example. 
     2977<p>Fixed pdo's GetInsertID() support. Thx Ricky Su. 
     2978<p>oci8 Prepare() now sets error messages if an error occurs. 
     2979<p>Added 'PT_BR' to SetDateLocale() -- brazilian portugese. 
     2980<p>charset in oci8 was not set correctly on *Connect() 
     2981<p>ADOConnection::Transpose() now appends as first column the field names. 
     2982<p>Added $ADODB_QUOTE_FIELDNAMES. If set to true, will autoquote field names in AutoExecute(),GetInsertSQL(), GetUpdateSQL(). 
     2983<p>Transpose now adds the field names as the first column after transposition. 
     2984<p>Added === check in ADODB_SetDatabaseAdapter for $db, adodb-active-record.inc.php. Thx Christian Affolter. 
     2985<p>Added ErrorNo() to adodb-active-record.inc.php. Thx ante#novisplet.com.

     2988 
     2989<p><a name="4.93"></a><b>4.93 10 Oct 2006</b> 
     2990<p>Added support for multiple database connections in performance monitoring code (adodb-perf.inc.php). Now all sql in multiple database connections can be saved into one database ($ADODB_LOG_CONN). 
     2991<p>Added MetaIndexes() to odbc_mssql. 
     2992<p>Added connection property $db->null2null = 'null'. In autoexecute/getinsertsql/getupdatesql, this value will be converted to a null. Set this to a funny invalid value if you do not want null conversion. See http://phplens.com/lens/lensforum/msgs.php?id=15902. 
     2993<p>Path disclosure problem in mysqli fixed. Thx Andy. 
     2994<p>Fixed typo in session_schema2.xml. 
     2995<p>Changed INT in oci8 to return correct precision in $fld->max_length, MetaColumns(). Thx Eloy Lafuente Plaza. 
     2996<p>Patched postgres64 _connect to handle serverinfo(). see http://phplens.com/lens/lensforum/msgs.php?id=15887. 
     2997<p>Added pdo fix for null columns. See http://phplens.com/lens/lensforum/msgs.php?id=15889 
     2998<p>For stored procedures, missing connection id now passed into mssql_query(). Thx Ecsy (ecsy#freemail.hu).

     3005 
     3006<p>Better odbtp date support. 
     3007<P>Added IgnoreErrors() to bypass default error handling. 
     3008<p>The _adodb_getcount() function in adodb-lib.inc.php, some ORDER BY bug fixes. 
     3009<p>For ibase and firebird, set  $sysTimeStamp = "CURRENT_TIMESTAMP". 
     3010<p>Fixed postgres connection bug: http://phplens.com/lens/lensforum/msgs.php?id=11057. 
     3011<p>Changed CacheSelectLimit() to flush cache when $secs2cache==-1 due to complaints from other users.  
     3012<p>Added support for using memcached with CacheExecute/CacheSelectLimit. Requires memcache module PECL extension. Usage: 
     3013<pre> 
     3014$db = NewADOConnection($driver); 
     3015$db->memCache = true; /// should we use memCache instead of caching in files 
     3016$db->memCacheHost = 126.0.1.1; /// memCache host 
     3017$db->memCachePort = 11211; /// this is default memCache port 
     3018$db->memCacheCompress = false; /// Use 'true' to store the item compressed (uses zlib) 
     3019 
     3020$db->Connect(...); 
     3021$db->CacheExecute($sql); 
     3022</pre> 
     3023<p>Implemented Transpose() for recordsets. Recordset must be retrieved using ADODB_FETCH_NUM. First column becomes the  
     3024column name. 
     3025<pre> 
     3026$DB = NewADOConnection('mysql'); 
     3027$DB->Connect(...); 
     3028$DB->SetFetchMode(ADODB_FETCH_NUM); 
     3029$rs = $DB->Execute('select productname,productid,unitprice from products limit 10'); 
     3030$rs2 = $DB->Transpose($rs); 
     3031rs2html($rs2); 
     3032</pre>

     3034<p>Major session code rewrite .... See session docs. 
     3035<p>PDO bindinputarray was not set properly for MySQL (changed from true to false). 
     3036<p>Changed CacheSelectLimit() to re-cache when $secs2cache==0. This is one way to flush the cache when SelectLimit is called. 
     3037<p>Added to quotes to mysql  and mysqli: "SHOW COLUMNS FROM `%s`"; 
     3038<p>Removed accidental optgroup handling in GetMenu(). 
     3039<a>Fixed ibase _BlobDecode for php5 compat, and also mem alloc issues for small blobs, thx salvatori#interia.pl 
     3040<p>Mysql driver OffsetDate() speedup, useful for adodb-sessions. 
     3041<p>Fix for GetAssoc() PHP5 compat. See http://phplens.com/lens/lensforum/msgs.php?id=15425 
     3042<p>Active Record - If inserting a record and the value of a primary key field is null, then we do not insert that field in as we assume it is an auto-increment field. Needed by mssql. 
     3043<p>Changed postgres7 MetaForeignKeys() see http://phplens.com/lens/lensforum/msgs.php?id=15531 
     3044<p>DB2 will now return db2_conn_errormsg() when it is a connection error.  
     3045<p><a name="4.90"></a><b>4.90 8 June 2006</b> 
     3046<p>Changed adodb_countrec() in adodb-lib.inc.php to allow LIMIT to be used as a speedup to reduce no of records counted. 
     3047<p>Added support for transaction modes for postgres and oci8 with SetTransactionMode().  
     3048These transaction modes affect all subsequent transactions of that connection. 
     3049<p>Thanks to Halmai Csongor for suggestion. 
     3050<p>Removed $off = $fieldOffset - 1 line in db2 driver, FetchField(). Tx Larry Menard.

     3052<p>Rounding in tohtml.inc.php did not work properly. Fixed. 
     3053<p>MetaIndexes in postgres fails when fields are deleted then added in again because the attnum has gaps in it.  
     3054See http://sourceforge.net/tracker/index.php?func=detail&aid=1451245&group_id=42718&atid=433976. Fixed. 
     3055<p>MetaForeignkeys in mysql and mysqli did not work when fetchMode==ADODB_FETCH_ASSOC used. Fixed. 
     3056<p>Reference error in AutoExecute() fixed. 
     3057<p>Added macaddr postgres type to MetaType. Maps to 'C'.

     289<h3>XML Schema Version 3</h3> 
     290<p>In March 2006, we added adodb-xmlschema03.inc.php to the release, which supports version 3 of XML Schema.  
     291The adodb-xmlschema.inc.php remains the same as previous releases, and supports version 2 of XML Schema.  
     292Version 3 provides some enhancements: 
     293 
     294<ul> 
     295     <li> Support for updating table data during an upgrade. 
     296     <li> Support for platform-specific table options and platform negation. 
     297     <li> Support for unsigned fields. 
     298     <li> Fixed opt and constraint support 
     299     <li> Many other fixes such as OPT tag, which allows you to set optional platform settings: 
     300</ul> 
     301 
     302<p>Example usage: 
     303<pre>&lt;?xml version="1.0"?> 
     304<b>&lt;schema version="0.3"></b> 
     305 &lt;table name="ats_kb">

     309  &lt;field name="organization_code" type="I4"/>  
     310  &lt;field name="sub_code" type="C" size="20"/> 
     311  etc... 
     312</pre> 
     313<p>To use it, change your code to include adodb-xmlschema03.inc.php. 
     314 
    264315<h3>Upgrading</h3> 
     316<p> 
    265317If your schema version is older, than XSLT is used to transform the 
    266318schema to the newest version. This means that if you are using an older

    45 <h3>Introduction</h3> 
    46 <p> We store state information specific to a user or web client in 
    47 session variables. These session variables persist throughout a 
     32<h2>Introduction</h2> 
     33<p> This document discusses the newer session handler adodb-session2.php. If 
     34  you have used the older adodb-session.php, then be forewarned that you will 
     35  need to alter your session table format. Otherwise everything is <a href="#compat">backward 
     36  compatible</a>. 
     37  Here are the <a href="docs-session.old.htm">older 
     38    docs</a> for 
     39  adodb-session.php.</p> 
     40<h2>Why Session Variables in a Database? </h2> 
     41<p>We store state information specific to a user or web 
     42    client in session variables. These session variables persist throughout a 
    4843session, as the user moves from page to page. </p> 
    4944<p>To use session variables, call session_start() at the beginning of 
    … …  
    6257  <li>Require notification when a session expires</li> 
    6358</ul> 
    64 <p>Then the ADOdb session handler provides you with the above 
     59<p>The ADOdb session handler provides you with the above 
    6560additional capabilities by storing the session information as records 
    6661in a database table that can be shared across multiple servers. </p> 
    67 <p><b>Important Upgrade Notice:</b> Since ADOdb 4.05, the session files 
    68 have been moved to its own folder, adodb/session. This is a rewrite 
    69 of the session code by Ross Smith. The old session code is in 
    70 adodb/session/old. </p> 
    71 <h4>ADOdb Session Handler Features</h4> 
     62<p>These records will be garbage collected based on the php.ini [session] timeout settings.  
     63You can register a notification function to notify you when the record has expired and  
     64is about to be freed by the garbage collector.</p> 
     65<p>An alternative to using a database backed session handler is to use <a href="http://www.danga.com/memcached/">memcached</a>. 
     66  This is a distributed memory based caching system suitable for storing session 
     67  information. 
     68  </p> 
     69<h2> The Improved Session Handler</h2> 
     70<p>In ADOdb 4.91, we added a new session handler, in adodb-session2.php. 
     71It features the following improvements: 
     72<ul> 
     73<li>Fully supports server farms using a new database table format. The 
     74  previous version used the web server time for timestamps, which can cause problems 
     75  on a system with multiple web servers with possibly inconsistent 
     76  times. The new version uses the database server time instead for all timestamps. 
     77<li>The older database table format is obsolete. The database table must be modified 
     78  to support storage of the database server time mentioned above. Also the field 
     79  named DATA has been changed to SESSDATA. In some databases, DATA is a reserved 
     80  word. 
     81<li>The functions dataFieldName() and syncSeconds() is obsolete. 
     82</ul> 
     83 
     84<p>Usage is  
     85 
     86<pre> 
     87include_once("adodb/session/adodb-session2.php"); 
     88ADOdb_Session::config($driver, $host, $user, $password, $database,$options=false); 
     89session_start(); 
     90 
     91<font 
     92 color="#004040">#<br># Test session vars, the following should increment on refresh<br>#<br>$_SESSION['AVAR'] += 1;<br>print "&lt;p&gt;\$_SESSION['AVAR']={$_SESSION['AVAR']}&lt;/p&gt;";</font> 
     93</pre> 
     94 
     95<p>When the session is created in session_start( ), the global variable $<b>ADODB_SESS_CONN</b> holds 
     96the connection object. 
     97<p>The default name of the table is sessions2. If you want to override it: 
     98   
     99<pre> 
     100include_once("adodb/session/adodb-session2.php"); 
     101$options['table'] = 'mytablename'; 
     102ADOdb_Session::config($driver, $host, $user, $password, $database,$options); 
     103session_start(); 
     104</pre> 
     105 
     106 
     107<h3>ADOdb Session Handler Features</h3> 
    72108<ul> 
    73109  <li>Ability to define a notification function that is called when a 
    … …  
    78114to the session data if there is a data change. </li> 
    79115  <li>Support for large amounts of session data with CLOBs (see 
    80 adodb-session-clob.php). Useful 
     116adodb-session-clob2.php). Useful 
    81117for Oracle. </li> 
    82118  <li>Support for encrypted session data, see 
    83 adodb-cryptsession.inc.php. Enabling encryption is simply a matter of 
    84 including adodb-cryptsession.inc.php instead of adodb-session.inc.php. </li> 
     119adodb-cryptsession2.php. Enabling encryption is simply a matter of 
     120including adodb-cryptsession2.php instead of adodb-session2.php. </li> 
    85121</ul> 
    86 <h3>Setup</h3> 
     122<h3>Session Handler Files </h3> 
    87123<p>There are 3 session management files that you can use: 
    88124</p> 
    89 <pre>adodb-session.php        : The default<br>adodb-session-clob.php   : Use this if you are storing DATA in clobs<br>adodb-cryptsession.php   : Use this if you want to store encrypted session data in the database<br><br>

    110  name="sessiontab"></a> <font color="#004040"><br>  create table sessions (<br>       SESSKEY char(32) not null,<br>       EXPIRY int(11) unsigned not null,<br>       EXPIREREF varchar(64),<br>       DATA text not null,<br>      primary key (sesskey)<br>  );</font><br>  
    111  </pre> 
    112  <p> For the adodb-session-clob.php version, create this: 
    113   <pre> 
    114     <font 
    115  color="#004040"><br>    create table sessions (<br>       SESSKEY char(32) not null,<br>       EXPIRY int(11) unsigned not null,<br>       EXPIREREF varchar(64),<br>       DATA CLOB,<br>      primary key (sesskey)<br>  );</font> 
    116  </pre> 
    117  <p>2. Then define the following parameters. You can either modify this file, or define them before this file is included: 
    118  <pre>      <font 
    119  color="#004040"><br>    $ADODB_SESSION_DRIVER='database driver, eg. mysql or ibase';<br>    $ADODB_SESSION_CONNECT='server to connect to';<br>    $ADODB_SESSION_USER ='user';<br>    $ADODB_SESSION_PWD ='password';<br>    $ADODB_SESSION_DB ='database';<br>    $ADODB_SESSION_TBL = 'sessions'; # setting this is optional<br>     </font> 
    120  </pre><p> 
    121      When the session is created, $<b>ADODB_SESS_CONN</b> holds the connection object.<br>    <br>  3. Recommended is PHP 4.0.6 or later. There are documented session bugs <br>  in earlier versions of PHP. 
    122 <h3>Notifications</h3> 
    123 <p>If you want to receive notification when a session expires, then tag 
    124 the session record with a <a href="#sessiontab">EXPIREREF</a> tag (see 
    125 the definition of the sessions table above). Before any session record 
    126 is deleted, ADOdb will call a notification function, passing in the 
    127 EXPIREREF. 
    128 </p> 
    129 <p>When a session is first created, we check a global variable 
    130 $ADODB_SESSION_EXPIRE_NOTIFY. This is an array with 2 elements, the 
     206  <font 
     207 color="#004040">CREATE TABLE SESSIONS2<br>(<br>   SESSKEY    VARCHAR2(48 BYTE)                  NOT NULL,<br>   EXPIRY     DATE                               NOT NULL,<br>   EXPIREREF  VARCHAR2(200 BYTE),<br>   CREATED    DATE                               NOT NULL,<br>   MODIFIED   DATE                               NOT NULL,<br>   SESSDATA   CLOB,<br>  PRIMARY KEY(SESSKEY)<br>); 
     208<br>CREATE INDEX SESS2_EXPIRY ON SESSIONS2(EXPIRY); 
     209CREATE INDEX SESS2_EXPIREREF ON SESSIONS2(EXPIREREF);</font></pre> 
     210<p> We need to use a CLOB here because for text greater than 4000 bytes long, 
     211  Oracle requires you to use the CLOB data type. If you are using the oci8 driver, 
     212  ADOdb will automatically enable CLOB handling. So you can use either adodb-session2.php 
     213  or adodb-session-clob2.php - in this case it doesn't matter. <br>     
     214<h2>Notifications</h2> 
     215<p>You can receive notification when your session is cleaned up by the session garbage collector or 
     216when you call session_destroy(). 
     217<p>PHP's session extension will automatically run a special garbage collection function based on 
     218your php.ini session.cookie_lifetime and session.gc_probability settings. This will in turn call 
     219adodb's garbage collection function, which can be setup to do notification. 
     220<p> 
     221<pre> 
     222        PHP Session --> ADOdb Session  --> Find all recs  --> Send          --> Delete queued 
     223        GC Function     GC Function        to be deleted      notification      records 
     224        executed at     called by                             for all recs 
     225        random time     Session Extension                     queued for deletion 
     226</pre> 
     227<p>When a session is created, we need to store a value in the session record (in the EXPIREREF field), typically  
     228the userid of the session. Later when the session has expired,  just before the record is deleted, 
     229we reload the EXPIREREF field and call the notification function with the value of EXPIREREF, which  
     230is the userid of the person being logged off. 
     231<p>ADOdb uses a global variable $ADODB_SESSION_EXPIRE_NOTIFY that you must predefine before session 
     232start to store the notification configuration.  
     233$ADODB_SESSION_EXPIRE_NOTIFY is an array with 2 elements, the 
    131234first being the name of the session variable you would like to store in 
    132235the EXPIREREF field, and the 2nd is the notification function's name. </p> 
    133 <p> Suppose we want to be notified when a user's session has expired, 
    134 based on the userid. The user id in the global session variable 
    135 $USERID. The function name is 'NotifyFn'. So we define: </p> 
    136 <pre> <font color="#004040"><br>        $ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');<br>    </font></pre> 
    137 And when the NotifyFn is called (when the session expires), we pass the 
    138 $USERID as the first parameter, eg. NotifyFn($userid, $sesskey). The 
     236<p>For example, suppose we want to be notified when a user's session has expired, 
     237based on the userid. When the user logs in, we store the id in the global session variable 
     238$USERID. The function name is 'NotifyFn'.  
     239<p> 
     240So we define (before session_start() is called): </p> 
     241<pre> <font color="#004040"> 
     242        $ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn'); 
     243</font></pre> 
     244And when the NotifyFn is called (when the session expires), the 
     245$USERID is passed in as the first parameter, eg. NotifyFn($userid, $sesskey). The 
    139246session key (which is the primary key of the record in the sessions 
    140247table) is the 2nd parameter. 
    141248<p> Here is an example of a Notification function that deletes some 
    142249records in the database and temporary files: </p> 
    143 <pre><font color="#004040"><br>        function NotifyFn($expireref, $sesskey)<br>        {<br>        global $ADODB_SESS_CONN; # the session connection object<br><br>          $user = $ADODB_SESS_CONN-&gt;qstr($expireref);<br>          $ADODB_SESS_CONN-&gt;Execute("delete from shopping_cart where user=$user");<br>          system("rm /work/tmpfiles/$expireref/*");<br>        }</font><br>    </pre> 
     250<pre><font color="#004040"> 
     251        function NotifyFn($expireref, $sesskey) 
     252        { 
     253                global $ADODB_SESS_CONN; # the session connection object 
     254                $user = $ADODB_SESS_CONN-&gt;qstr($expireref); 
     255                 
     256                $ADODB_SESS_CONN-&gt;Execute("delete from shopping_cart where user=$user");           
     257                system("rm /work/tmpfiles/$expireref/*"); 
     258        }</font>   
     259                          </pre> 
    144260<p> NOTE 1: If you have register_globals disabled in php.ini, then you 
    145261will have to manually set the EXPIREREF. E.g. </p> 
    146262<pre> <font color="#004040"> 
    147     $GLOBALS['USERID'] =&amp; $_SESSION['USERID']; 
    148     $ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');</font> 
     263$GLOBALS['USERID'] = GetUserID(); 
     264$ADODB_SESSION_EXPIRE_NOTIFY = array('USERID','NotifyFn');</font> 
    149265</pre> 
    150266<p> NOTE 2: If you want to change the EXPIREREF after the session 
    … …  
    152268to force a database record update. 
    153269</p> 
    154 <h4>Neat Notification Tricks</h4> 
     270<h3>Neat Notification Tricks</h3> 
    155271<p><i>ExpireRef</i> normally holds the user id of the current session. 
    156272</p> 
    … …  
    166282can be logged in twice. Useful for security reasons. 
    167283</p> 
    168 <h3>Compression/Encryption Schemes</h3> 
     284<h2>Compression/Encryption Schemes</h2> 
    169285Since ADOdb 4.05, thanks to Ross Smith, multiple encryption and 
    170286compression schemes are supported. Currently, supported are: 
    … …  
    172288<pre>  MD5Crypt (crypt.inc.php)<br>  MCrypt<br>  Secure (Horde's emulation of MCrypt, if MCrypt module is not available.)<br>  GZip<br>  BZip2<br></pre> 
    173289<p>These are stackable. E.g. 
    174 <p><pre>ADODB_Session::filter(new ADODB_Compress_Bzip2());<br>ADODB_Session::filter(new ADODB_Encrypt_MD5());<br></pre> 
     290<pre>ADODB_Session::filter(new ADODB_Compress_Bzip2());<br>ADODB_Session::filter(new ADODB_Encrypt_MD5());<br></pre> 
    175291will compress and then encrypt the record in the database. 
    176 <p>Also see the <a href="docs-adodb.htm">core ADOdb documentation</a>. 
    177 </p> 
     292<h2>Session Cookie Regeneration: adodb_session_regenerate_id()</h2> 
     293<p>Dynamically change the current session id with a newly generated one and update 
     294  database. Currently only works with cookies. Useful to improve security by 
     295  reducing the risk of session-hijacking. See this article on <a href=http://shiflett.org/articles/security-corner-feb2004>Session 
     296  Fixation</a> for more info  
     297on the theory behind this feature. Usage:<pre> 
     298        include('path/to/adodb/session/adodb-session2.php'); 
     299         
     300        session_start(); 
     301        # Approximately every 10 page loads, reset cookie for safety. 
     302        # This is extremely simplistic example, better  
     303        # to regenerate only when the user logs in or changes 
     304        # user privilege levels. 
     305        if ((rand()%10) == 0) adodb_session_regenerate_id();  
     306</pre> 
     307<p>This function calls session_regenerate_id() internally or simulates it if the function does not exist. 
     308<h2>Vacuum/Optimize Database</h2> 
     309<p>During session garbage collection, if postgresql is detected, 
     310  ADOdb can be set to run VACUUM. If mysql is detected, then optimize database 
     311  could be called.You can turn this on or off using:</p> 
     312<pre>$turnOn = true; # or false 
     313ADODB_Session::optimize($turnOn); 
     314</pre> 
     315<p>The default  is optimization is disabled.</p> 
     316<h2><a name=compat></a>Backwards Compatability </h2> 
     317<p>The older method of connecting to ADOdb using global variables is still supported:</p> 
     318<pre> $ADODB_SESSION_DRIVER='mysql'; 
     319 $ADODB_SESSION_CONNECT='localhost'; 
     320 $ADODB_SESSION_USER ='root'; 
     321 $ADODB_SESSION_PWD ='abc'; 
     322 $ADODB_SESSION_DB ='phplens'; 
     323  
     324 include('path/to/adodb/session/adodb-<strong>session2</strong>.php'); </pre> 
     325<p>In the above example, the only things you need to change in your code to upgrade 
     326  is </p> 
     327<ul> 
     328  <li>your session table format to the new one.</li> 
     329  <li>the include file from adodb-session.php to adodb-session2.php. </li> 
     330</ul> 
     331<h2>More Info</h2> 
     332<p>Also see the <a href="docs-adodb.htm">core ADOdb documentation</a>. And if 
     333  you are interested in the obsolete adodb-session.php, see <a href="docs-session.old.htm">old

     97  mssql driver.  
     98</p><p>The property $emptyDate missing from connection class. Also changed 1903 to  
     99  constant (TIMESTAMP_FIRST_YEAR=100). Thx to Sebastiaan van Stijn.  
     100</p><p>ADOdb speedup optimization - we now return all arrays by reference.
