No, it has two different outputs, one for PHP 7, one for PHP 8.

It also has two different deprecation notices, one concerning the 
behavioral change between PHP 7 and PHP 8 we're seeing and one 
concerning an upcoming behavioral change with PHP 9.

However in all PHP versions the function call clearly is non-sense, 
because 'null' clearly cannot be a substring of a string, as it is a 
completely unrelated data type.
