Bug: FILTER_SANITIZE_STRING is deprecated (PHP 8.1.0 early test)

[sys4soft]

Hi there.

I'm currently testing a PHP 8.1.0 master branch Windows compilation, which will certainly be very close to the final version of PHP 8.1.0, and CodeIgniter 4.1.3.

In the development environment, this error is coming up:

SYSTEMPATH\Router\RouteCollection.php at line 1368
line: 1368 $from = filter_var($prefix . $from, FILTER_SANITIZE_STRING);
ErrorException: Constant FILTER_SANITIZE_STRING is deprecated

It seems to me that this would be a good time to prepare for the future by fixing this "future" bug that is coming.

I will not post any "future bugs" here again unless you expressly direct me to do so, as it may not be a priority at this time to focus on the solution.

Let me know if you want me to identify potential "future bugs" as I test with unreleased versions of PHP.

Specs:
Using Laragon (Apache 2.4.35 + PHP 8.1.0 master branch compilation)

Hi, thanks for early testing. Please direct all found issues under #4883 so we can consolidate all issues. I'll close this first as this is not a bug but a compat issue. Thanks anyway.
