I have this this multilevel array :

$productpacks . Example $productpacks[0][0] is 4355 .

Now, I have another array that is simple : $codescart[] . Example $codescart[0] is 4355 .

I am trying to differ those two like this (it does not seem to work) :

foreach($productpacks as $pack) {
    $diff = array_diff($pack, $codescart);
    if (empty($diff)) {
        // $cart contains this pack
    }
}

Does that work for anybody ? or were is the problem if any ...

Please post example data as an initialization script if you want us to test. Just knowing that $productpacks[0][0] is 4355 is not enough... tx — Mathieu Dumoulin

Why not just use in_array()?

foreach($productpacks as $pack) {
  if (in_array($pack, $codescart)) {
    // $cart contains this pack
  }
}
