Description

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.
