We scroll to the beginning of the new recordset	after processing.	We pass a recordset and function name to RSFilter($rs,'rowfunc');	and the function will be called multiple times, once	for each row in the recordset. The function will be passed	an array containing one row repeatedly.	Example:	// ucwords() every element in the recordset	function do_ucwords(&$arr,$rs)	{		foreach($arr as $k => $v) {			$arr[$k] = ucwords($v);		}	}	$rs = RSFilter($rs,'do_ucwords'); */function &RSFilter($rs,$fn){	if ($rs->databaseType != 'array') {		if (!$rs->connection) return false;		$rs = &$rs->connection->_rs2rs($rs);	}	$rows = $rs->RecordCount();	for ($i=0; $i < $rows; $i++) {		if (is_array ($fn)) {        	$obj = $fn[0];        	$method = $fn[1];        	$obj->$method ($rs->_array[$i],$rs);      } else {			$fn($rs->_array[$i],$rs);      }	}	if (!$rs->EOF) {		$rs->_currentRow = 0;		$rs->fields = $rs->_array[0];	}	return $rs;}?>
