A lot to take in with that title I know, what I'm trying to do I don't believe to be too complicated but I'm having a hard time understanding something. Is what I'm trying to do is create a multidimensional array of data that I will use to dynamically call a function using:

call_user_func_array($function, $variables)

Now here's how I have my array setup.

I have 3 main named keys (representing the name of the functions):

 string, numeric, username.

In these arrays I have the variables that will be passed to each one of those functions:

username which I need to take 2 additional parameters that I use another nested array to take care of.
password which I also need to take 2 additional parameters.
confirmPassword which I need 2 additional parameters for.

So I need it to look something like this when all the code is done computing:

 call_user_func_array(string($username, @param1, @param2));
 call_user_func_array(string($password, @param1, @param2));
 call_user_func_array(string($confirmPassword, @param1, @param2));
 call_user_func_array(string($firstName));
 call_user_func_array(string($lastName));
 call_user_func_array(numeric($memberLevel));
 call_user_func_array(numeric($memberId));
 call_user_func_array(username($username));

Here's the code with the data and the functions and variables:

		$data = array (
				'username'        => 'username',
				'password'        => md5('pass'),
				'confirmPassword' => md5('pass'),
				'firstName'       => 'firstname',
				'lastName'        => 'lastname',
				'memberLevel'     => '2',
				'memberId'		  => '4',
		);
		$val_array = array(
				'string'			=> array(
					array('username', 3, 4), 
					array('password', 4, 3), 
					array('confirmPassword', 4, 3), 
					'firstName', 'lastName'),
				'numeric'			=> array('memberLevel', 'memberId'),
				'username'			=> array('username'),
			);
		$error = array();

	foreach ($val_array as $var => $val_err) {

		// if (is_array($val_array[$var])) {
		// }
		$function = $var;

		foreach ($val_err as $var) {

			//$error[] = $var;
			echo "validate_".$function."(".$data[$var].")\n";
		}
	}

Am I making any sense to anybody? Thanks guys.

    Here's what I used to test it and it seems to pull the the arguments and function names correctly, It doesn't seem to like the duplicate username key, if I remove the second one with just username => array('username') it will print the username key above it, however if I leave it in it doesn't print either. Also, lastname only has a 2 after it where is the 2 coming from?

    Screen output (errors and echos):

    username1a1dc91c907325c69271ddf0c944bc72
4
3
1a1dc91c907325c69271ddf0c944bc72
4
3
firstname

32
lastname2

    New code:

            $data = array (
                'username'        => 'username',
                'password'        => md5('pass'),
                'confirmPassword' => md5('pass'),
                'firstName'       => 'firstname',
                'lastName'        => 'lastname',
                'memberLevel'     => '2',
                'memberId'        => '4',
        );
	$val_array = array(
	      'username' => array('string', 3, 4),
	      'username' => array('username'),
	      'password' => array('string', 4, 3),
	      'confirmPassword' => array('string', 4, 3),
	      'firstName' => array('string', 0, 32),
	      'lastName' => array('string', 0, 32),
	      'memberLevel' => array('numeric'),
	      'lastName' => array('numeric'),
	);

    foreach($val_array as $name => $args) {
        $type = $args[0];
        $args[0] = $data[$name];
        call_user_func_array("validate_$type", $args);
    }

    function validate_string($str, $i, $j) {
        echo $str . "<br />";
        echo $i . "<br />";
        echo $j . "<br />";
    }

    function validate_numeric($num) {
      echo $num;
    }

    function validate_username($str) {
        echo $str;
    }

      You're going to have to rethink your approach somewhat. By definition, all keys of an array must be unique.
