/** * A wrapper for PHP's parse_url() function that handles consistency in the return values * across PHP versions. * * PHP 5.4.7 expanded parse_url()'s ability to handle non-absolute URLs, including * schemeless and relative URLs with "://" in the path. This function works around * those limitations providing a standard output on PHP 5.2~5.4+. * * Secondly, across various PHP versions, schemeless URLs containing a ":" in the query * are being handled inconsistently. This function works around those differences as well. * * @since 4.4.0 * @since 4.7.0 The `$component` parameter was added for parity with PHP's `parse_url()`. * * @link https://www.php.net/manual/en/function.parse-url.php * * @param string $url The URL to parse. * @param int $component The specific component to retrieve. Use one of the PHP * predefined constants to specify which one. * Defaults to -1 (= return all parts as an array). * @return mixed False on parse failure; Array of URL components on success; * When a specific component has been requested: null if the component * doesn't exist in the given URL; a string or - in the case of * PHP_URL_PORT - integer when it does.
