如何解析youtube网址以获取视频或播放列表ID？

Question

I'm looking for a way to extract both (partials) youtube urls and single ids from a user input string.
This article How do I find all YouTube video ids in a string using a regex? got me going quite well but still i'm struggling a bit.

Is there a way to find both playlist and/or video ids from a strings from:

Answer 1

use:

$urlInfo = parse_url($url); // to get url components (scheme:host:query)

$urlVars = array();
parse_str($queryString, $urlVars); // to get the query vars 

check out the youtube api for more details on the format
