What if you have an array like this: Array ( [0] => Array

       (
           [0] => 1
           [1] => 2
           [2] => 2
           [3] => 2
           [4] => 2
           [5] => 4
       )

[1] => 4 [2] => 2 [3] => 4 ) And i want to remove the 4, but i don't know 1 and 3. using array_flip wouldn't work because of my multi-dimensional array. But what if i'm using array_search? will it return 1 only? will it return 5?

Why in the world you'd architect the array with a value when you need to unset by value in the first place is beyond me, though...

Sometimes you end up with such arrays, where you need to have non-unique values first, so you store them in the value, and then you need to remove some of the non-unique values. But it's a multi-dimensional array... Tijnema

That works when you know the key, but will that work when you only know the value? Tijnema

Hi, Is there currently a function that removes a key/value from an

array?

I use this code right now: function array_remove($array,$remove,$remove_value = true) {

      foreach($array as $key => $value) {
              if($remove_value && $value != $remove) {
                      $new_array[$key] = $value;
              } elseif (!$remove_value && $key != $remove) {
                      $new_array[$key] = $value;
              }
      }
      return $new_array;

} array_remove(array(1=>2,2=>3),2,true); // array (2=>3) array_remove(array(1=>2,2=>3),2,false); // array (1=>2) Anyone knows if there already exists such function? Else should i create future request? Tijnema -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
