php - 从YouTube网址获取视频ID的模式

Question

我尝试按照以下模式从YouTube网址获取YouTube ID。似乎适用于普通的youtube URL，

$pattern = 
        '%^# Match any youtube URL
        (?:https?://)?  # Optional scheme. Either http or https
        (?:www\.)?      # Optional www subdomain
        (?:             # Group host alternatives
          youtu\.be/    # Either youtu.be,
        | youtube\.com  # or youtube.com
          (?:           # Group path alternatives
            /embed/     # Either /embed/
          | /v/         # or /v/
          | /&v=/       # or ?feature=youtu.be&v=NXwxHU2Q0bo
          | /watch\?v=  # or /watch\?v=
          )             # End path alternatives.
        )               # End host alternatives.
        ([\w-]{10,12})  # Allow 10-12 for 11 char youtube id.
        $%x'
        ;
        $result = preg_match($pattern, $url, $matches);
        if ($result) {
            return $matches[1];
        }

但是此URL https://www.youtube.com/watch?feature=youtu.be&v=NXwxHU2Q0bo失败
和
https://m.youtube.com/watch?v=w7P_F7DGPU0

要从上述URL获取视频ID，需要包含什么模式？

这是解决方案:

^# Match any youtube URL
    (?:https?://)?  # Optional scheme. Either http or https
    (?:
        www\. # Optional www subdomain
      | m\.   # Optional mobile subdomain
    )?      
    (?:             # Group host alternatives
      youtu\.be/    # Either youtu.be,
    | youtube\.com  # or youtube.com
      (?:           # Group path alternatives
        /           # Shortlink
      | /embed/     # Either /embed/
      | /v/         # or /v/
      | /&v=/       # or ?feature=youtu.be&v=NXwxHU2Q0bo
      | /watch\?v=  # or /watch\?v=
      | /watch\?feature=youtu\.be&v= # alternativ link with watch
      )             # End path alternatives.
    )               # End host alternatives.
    ([\w-]{10,12})  # Allow 10-12 for 11 char youtube id.
    $
