Question

Can any one please either advice or point me in the right director for how to strip strings out of strings.

In my case I have this variable.

$videoEmbed = the_sub_field('video_embed_code');

which is essentially this string (example)…

<iframe width="560" height="315" src="http://www.youtube.com/embed/2RR-tzGOyi0" frameborder="0" allowfullscreen></iframe>

My question is can the src attribute value be extracted? But using php and not javascript.

Any pointers or help would be most awesome.

Thanks

You can use DOMDocument:

<?php 
$videoEmbed = '<iframe width="560" height="315" src="http://www.youtube.com/embed/2RR-tzGOyi0" frameborder="0" allowfullscreen></iframe>';
$doc = new DOMDocument();
$doc->loadHTML($videoEmbed);

$src = $doc->getElementsByTagName('iframe')->item(0)->getAttribute('src');

echo $src;

?>
