Nested for loops and arrays

[heaps21]

Hi, I have 2 arrays of usernames and I want to create a new array containing usernames that are in array1 that arent in array2. It sounds simple in theory but i just cant figure out the logic of how to do it (although I was thinking along the lines of nested for loops). Can any one help?
Cheers.

try this: http://www.php.net/manual/en/function.array-merge.php

given 2 arrays, $array1 and $array2....

<?php


function get_unique($username) {

   gobal array2;
   foreach ($array2 as $value) {
      if ($username == $value) {
         return();
      } 
   }
   
   return($username);

}


$new_array = array_filter($array1,"get_unique");

(that *SHOULD* work... ;-P)..

Hint: Use array_diff (http://de.php.net/array_diff).
