Use an array as an alternate method of sending/returning data to the second argument.
function escape($id, &$data) {
if ( is_array($data) ) {
foreach ( $data AS $k => $v ) {
escape($id, $v);
$data[$k] = $v;
}
} else {
$data = mysql_real_escape_string($data, $id);
}
}
This would handle any number of nested arrays/datasets.
Hope it helps.
