16 | Filter all fields and all rows in a recordset and returns the
|
---|
17 | processed recordset. We scroll to the beginning of the new recordset
|
---|
18 | after processing.
|
---|
19 |
|
---|
20 | We pass a recordset and function name to RSFilter($rs,'rowfunc');
|
---|
21 | and the function will be called multiple times, once
|
---|
22 | for each row in the recordset. The function will be passed
|
---|
23 | an array containing one row repeatedly.
|
---|
24 |
|
---|
25 | Example:
|
---|
26 |
|
---|
27 | // ucwords() every element in the recordset
|
---|
28 | function do_ucwords(&$arr,$rs)
|
---|
29 | {
|
---|
30 | foreach($arr as $k => $v) {
|
---|
31 | $arr[$k] = ucwords($v);
|
---|
32 | }
|
---|
33 | }
|
---|
34 | $rs = RSFilter($rs,'do_ucwords');
|
