Question

我有这个 iframe

<iframe width="425" height="349" src="http://www.youtube.com/embed/YRUG-Pu7RzE" frameborder="0" allowfullscreen></iframe>

如何通过正则表达式或任何方式从中获取视频 id......

Answer 1

您可以使用：

$subject = '<iframe width=\"425\" height=\"349\" src=\"http://www.youtube.com/embed/YRUG-Pu7RzE\" frameborder=\"0\" allowfullscreen></iframe>';
$pattern = '!http://(?:www.)?youtube.com/embed/([^"']+)!i';
$result = preg_match($pattern, $subject, $subpattern); 

$subpattern 将包含：

Array ( [0] => http://www.youtube.com/embed/YRUG-Pu7RzE [1] => YRUG-Pu7RzE )
