 New Comment:

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.

Description:
------------
---
From manual page: https://php.net/function.stripos
---
The function returns [0] instead of [false] if it is searched agains an empty string ''

Prior to PHP 8 the function returned [false]

Test script:
---------------
var_dump( stripos( 'http://example.com',
'' ) );

Expected result:
----------------
false

Actual result:
--------------
0
