Another way of passing references with a dynamic number of arguments: (This example is limited to 10 arguments) <?php define('NULL_ARG', 'DUMMY_ARGUMENT'); function refArg($arg0 = NULL_ARG, $arg1 = NULL_ARG, $arg2 = NULL_ARG, $arg3 = NULL_ARG, $arg4 = NULL_ARG, $arg5 = NULL_ARG, $arg6 = NULL_ARG, $arg7 = NULL_ARG, $arg8 = NULL_ARG, $arg9 = NULL_ARG) { for ($args=array(), $i=0; $i < 10; $i++) { $name = 'arg' . $i; if ($i < func_num_args()) { $args[$i] = &$$name; } unset($$name, $name); } $args[0] = 'Modified.'; } $test = 'Not modified.<br>'; refArg(&$test); echo $test; // Prints 'Modified' ?> -- http://www.php.net/manual/en/function.func-get-args.php http://master.php.net/manage/user-notes.php?action=edit+18350 http://master.php.net/manage/user-notes.php?action=delete+18350 http://master.php.net/manage/user-notes.php?action=reject+18350
