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

Just use the filter extension.

/* prevent XSS. */
$_GET   = filter_input_array(INPUT_GET, FILTER_SANITIZE_STRING);
$_POST  = filter_input_array(INPUT_POST, FILTER_SANITIZE_STRING);

This will sanitize your $_GET and $_POST.
