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. Reference: [https://www.php.net/manual/en/function.parse-url.php#refsect1-function.parse-url-returnvalues PHP Manual: parse_url(): Return Values] In this case, `parse_url()` is called with the `PHP_URL_PATH` as `$component`. This will return `null` in the majority of cases, as – exсept for subdirectory-based sites – `home_url()` returns a URL without the trailing slash, like `http://example.org`. The return value of `parse_url()` was subsequently passed to `trim()`, leading to a `trim(): Passing null to parameter #1 ($string) of type string is deprecated` notice on PHP 8.1. Fixed by adjusting the logic flow to: * Only pass the return value of `parse_url()` to follow-on functions if it makes sense, i.e. if it isn't `null`, nor an empty string. * Preventing calls to `preg_replace()` and `trim()` further down in the function logic flow, when `preg_replace()`/`trim()` would have nothing to do anyhow. Follow-up to [25617]. Props jrf, hellofromTonya, SergeyBiryukov. See #53635.
