where to paste php code to apply for all sites?

[Krishna]

Hi,
I want to sanitize user input for all my sites.
So, I want to keep this code in openlitespeed lsphp82 somewhere so that it applies to all my websites :

I want to run this php code at the beginning of all my php scripts.

foreach ($_GET as $key => $value) {

    $_GET[$key] = filter_var($value, FILTER_SANITIZE_STRING);

}

Instead of editing all the php files of all my websites, is there an easy way?
please suggest.
Thanks

You can try to add the following rule into the web admin> VH > General > php.ini Override

php_value auto_prepend_file script.php

Or add it to the php.ini so it will apply globally.
