  23  	 Filter all fields and all rows in a recordset and returns the
  24  	 processed recordset. We scroll to the beginning of the new recordset
  25  	 after processing.
  26  
  27  	 We pass a recordset and function name to RSFilter($rs,'rowfunc');
  28  	 and the function will be called multiple times, once
  29  	 for each row in the recordset. The function will be passed
  30  	 an array containing one row repeatedly.
  31  
  32  	 Example:
  33  
  34  	 // ucwords() every element in the recordset
  35  	 function do_ucwords(&$arr,$rs)
  36  	 {
  37  	 	 foreach($arr as $k => $v) {
  38  	 	 	 $arr[$k] = ucwords($v);
  39  	 	 }
  40  	 }
  41  	 $rs = RSFilter($rs,'do_ucwords');
