PHP 8 supports empty needles in string search functions, and no longer treats them as an error condition. For most functions this previously resulted in a warning (https://3v4l.org/jBWnA), stripos() is an exception to that rule.

Noted on https://www.php.net/manual/en/migration80.incompatible.php:

> The needle argument for strpos(), strrpos(), stripos(), strripos(), strstr(), stristr() and strrchr() can now be empty.
