+/**
+ * A wrapper for PHP's parse_url() function that handles edgecases in < PHP 5.4.7
+ *
+ * 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 works around those
+ * limitations providing a standard output on PHP 5.2~5.4+.
+ *
+ * Error suppression is used as prior to PHP 5.3.3, an E_WARNING would be generated
+ * when URL parsing failed.
+ *
+ * @since 4.4.0
+ *
+ * @param string $url The URL to parse.
+ * @return bool|array False on failure; Array of URL components on success;
+ *                    See parse_url()'s return values.
