$path = set_include_path(get_include_path() . PATH_SEPARATOR .implode(PATH_SEPARATOR,$modules));

spl_autoload_register("spl_autoload", false);

Answer 1

If you only want to use the default spl_autoload() implementation, I would suggest passing null as the first argument as per PHP documentation: https://www.php.net/manual/en/function.spl-autoload-register.php#refsect1-function.spl-autoload-register-parameters

Answer 2

As this comment on the PHP manual says:

Since PHP 8.0 spl_autoload_register() will always throw a TypeError on invalid arguments, therefore the second argument throw is ignored and a notice will be emitted if it is set to False.

So on PHP 8 you should no longer pass false as the 2nd argument.

Answer 3

just replace

spl_autoload_register("spl_autoload", false);

with

spl_autoload_register("spl_autoload");
