Here is a very simple function to run stripslashes on an array and all of its child arrays. The function below is for PHP 5 and takes a single argument which should consist of an array. It loops through all elements of the array, and if an element is an array, it calls itself on the child array to an infinite depth. Of course this can cause memory problems if your arrays are dynamically created with an excessively large depth, but for most uses, it will function perfectly.

The Code

function unstrip_array($array){
    foreach($array as &$val){
        if(is_array($val)){
            $val = unstrip_array($val);
        }else{
            $val = stripslashes($val);
        }
    }
return $array;
}

Why would I need to unstrip an entire array?

It’s useful for WordPress Plugin developers or anyone whose scripts might be run on a server with magic quotes enabled. It is also excellent to strip any slashes from $_POST inputs that might confuse your attempts to escape the strings later. Running an array of post data through this will make it easier to ensure that you don’t have hacking attempts.
