Fix Deprecated Warning for trim() on Null Values

Description

This PR resolves a PHP 8.1+ deprecation warning caused by passing null to trim() in the redirect() function. The issue resulted in the following error:

PHP Deprecated: trim(): Passing null to parameter ($string) of type string is deprecated

Fix

• Cast $userrequest and $storedrequest to (string) before passing them to trim().
• Ensures compatibility with newer PHP versions while maintaining expected behavior.

Changes

Updated the redirect() function:

} elseif (urldecode(trim((string) $userrequest, '/')) == trim((string) $storedrequest, '/')) {

Testing
Verified that redirects still function correctly.
Tested under PHP 7.x and 8.x to ensure compatibility.
Impact
✅ Eliminates the deprecation notice.
✅ Prevents potential issues in future PHP releases.
