[php-src] Issue #7890: parse_url() and incorrect port definition

Issue: https://github.com/php/php-src/issues/7890 Comment Author: KapitanOczywisty Before port you can have only double slash - if there is anything more - it's not a port. I think it's still possible to write proper url parsing which can handle invalid urls, but it cannot relay on : as a major part, it should be some state-based algorithm. [NodeJS implementation](https://github.com/nodejs/node/blob/f6e5050579d8d0ec7c68ed499dcc8701bd49c18a/src/node_url.cc#L815) could probably parse invalid urls, but it's way more complex. Even league/uri package is capable of parsing broken URLs. Maybe this is the place for replacement of parse_url with object-based internal extension. new URL(...) with isValid etc, but with performance of native modules.
