One method looks for videos. When testing a youtube video page the video is scraped and is displayed just fine. Source code looks something like:

What I would like to know is, how can I stop this video from autoplaying? I have tried various ways of adding autoplay=0 after the src etc with no luck.

Has anyone had experience with the method I’m using? Is it technically viable?

Thanks

Answer 1

You are over-complicating things, You should grab the youtube video ID with a little regex:

if(preg_match('/(?<=video_id=).*?(?=&|")/',$str,$matches)){
    $video_id = $matches[0];
}

And then use it to create the real embed code:

$youtube = '<iframe width="853" height="480" src="http://www.youtube.com/embed/'.$video_id.'?hd=1" frameborder="0" allowfullscreen></iframe>'

And then it never auto-plays
