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 url’s, including schemeless and relative url’s 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 starting containing a ":" in the query are being handled inconsistently. This function works around those differences as well.
Error suppression is used as prior to PHP 5.3.3, an E_WARNING would be generated when URL parsing failed.
(string) (Required) The URL to parse.
(int) (Optional) 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).
Default value: -1
(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. See parse_url()'s return values.
