PHP -Sanitize values of a array

Question

I have a array, which comes from $_POST[] and can have other arrays in it as values, like:

array(
 \'title\' => \'Title\',
 \'data\' => ar         


        

Answer 1

function strip($string, $allowed_tags = NULL)
{
    if (is_array($string))
    {
        foreach ($string as $k => $v)
        {
            $string[$k] = strip($v, $allowed_tags);
        }
        return $string;
    }

    return strip_tags($string, $allowed_tags);
}

Just an example of a recursive function, for stripping tags in this case.

$arr = strip($arr);
