嵌入youtube视频参数被忽略

Question

I use the following code to replace youtube urls to embed links in order to display them as videos. But I have come to a problem where I can't view videos from links having more parameters other than ?v=video_code

php code:

function embedYoutube($text)
{

    $pattern = '|http://www\.youtube\.com/watch\?.*?\bv=([^ ]+)|';
    $replacement = '<div style="width:100%;float:left;margin-top:15px;margin-bottom:15px;"><iframe width="570" height="315" src=http://www.youtube.com/embed/$1 frameborder="0" allowfullscreen></iframe></div>';
    return preg_replace($pattern, $replacement, $text, 1);

}

Answer 1

Update your regex to match only the v parameter, and before the first &:

|http://www\.youtube\.com/watch\?.*?\bv=([^ ]+)\&?|
