Seems the array_key_exists can't find a key in a multidimensional array...

Here's my fix...

<?php

function multi_array_key_exists($needle, $haystack) {
  foreach ($haystack as $key=>$value) {
    if ($needle==$key) {
      return true;
    }
    if (is_array($value)) {
      multi_array_key_exists($needle, $value);
    }
  }
  return false;
}

?>

Kode 

function get_key_path($needle, &$haystack){
  /*
    created by:J. P. Svensson
    This function returns the key path to a needle in a multidimensional array. 
    The returned value is an array of keys where the keys comes in reversed order in the array,if the needle ain't found false is returned.
    */
  foreach ($haystack as $key=>$value) {
    if ($needle==$value) {
	  $p=array();
	  $p[]=$key;
      return $p;
    }
    if(is_array($value)) {
      $p=get_key_path($needle, $value);
	  if($p!==FALSE){
	    $p[]=$key;
	    return $p;
	  }
    }
  }
  return false;
}
