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'); |
---|
