How to transform this img code like this in php (regex pattern) [duplicate]

Question

This is my HTML code:

<img src="http://img.youtube.com/vi/ErIRt52MOkE/0.jpg" class="mceItem" alt="ErIRt52MOkE"/>

And I want transform this code like this:

<iframe title="YouTube video player" width="640" height="390" src="http://www.youtube.com/embed/ErIRt52MOkE" frameborder="0" allowfullscreen></iframe>

This my pattern: (Message: preg_replace() [function.preg-replace]: Unknown modifier 'v')

<img(?=[^>]+?class="mceItem")(?=[^>]+?alt="[\w]+?")[^>]+?img.youtube.com/vi/([\w]+?)/0.jpg[^>]*?/>

Yes, that's possible. There are other questions like this. Use the search function to find other tips. Then update your question with attempts you made, so it gets a little less broad or a plain coding inquiry. — mario

Well, escape your delimiters. Or use e.g. # instead of /. — mario

Try this:-

<?php
  preg_match_all('%youtube\.com\/vi\/([^\/]+)%','<img src="http://img.youtube.com/vi/ErIRt52MOkE/0.jpg" class="mceItem" alt="ErIRt52MOkE"/>',$matches);

  print_r($matches);

  $outputStr = '<iframe title="YouTube video player" width="640" height="390" src="http://www.youtube.com/embed/'.$matches[1][0].'" frameborder="0" allowfullscreen></iframe>';

  echo $outputStr;
?>
