Walk through entire multidimensional array?

[dbzfyam]

Does anyone know if it is possible to walk through an entire multidimensional array (in this case the $_POST array)? I need this to 'sanitize' it a bit (remove script tags for example). Sample array:

Array
(
 [userID] => 1
 [userAddress] => "street"
 [userPostal] => "12345"
 [userCity] => "NY"
 [userCountry] => "US"
 [payment] => Array
 (
 [type] => "mastercard"
 [number] => "12345678"
 [cart] => Array
  (
   [0] => Array
    (
     [ID] => 1
     [amount] => 31231
     [comment] => ""
    )
   [1] => Array
    (
     [ID] => 13
     [score] => 15611
     [comment] => ""
    )
   [2] => Array
    (
     [ID] => 15
     [score] => 9151
     [comment] => ""
    )
  )
)

I need to check all of those. I've looked at array_walk_recursive and array_walk but have no idea how to use those with a multidimensional array.

Thanks in advance,
Stefan

how about doing nested for loops. It may not be the most efficient way to go about it, but it should do the job.

function multiDimensionalArrayMap($func,$arr) {
$newArr = array();
if (!empty($arr)) {
foreach($arr AS $key => $value) {
$newArr[$key] = (is_array($value) ? multiDimensionalArrayMap($func,$value) : $func($value));
}
}
return $newArr;
}

$_POST = multiDimensionalArrayMap('yourFunctionHere',$_POST);

Thanks for the fast replies! I just tried dc's script and it's working perfectly! I did try something like that but somehow the array got scrambled (too bad I deleted it). Thanks for the help!
