Subject: [PATCH] PHP 8.1: Tests_Functions_DoEnclose: fix bug in test

As per the PHP manual:
> If the component parameter is omitted, an associative array is returned.
> If the component parameter is specified, parse_url() returns a string (or an int, in the case of PHP_URL_PORT) instead of an array. If the requested component doesn't exist within the given URL, null will be returned.

Ref: https://www.php.net/manual/en/function.parse-url.php#refsect1-function.parse-url-returnvalues

In this case, `parse_url()` is called with the `PHP_URL_PATH` as `$component`, but the returned value is subsequently checked against `false`.
In other words, this condition would previously always result `true` and would lead to `null`, potentially, being passed to the PHP native `pathinfo()` function which expects a string.

On PHP 8.1, this will result in a test failure with a `pathinfo(): Passing null to parameter #1 ($path) of type string is deprecated` error.
