Question

I want to replace this line :

<img width="600" height="256" alt="javascript00" src="http://localhost/img/test.png" title="javascript00" class="aligncenter size-full wp-image-1973">

With this :

<p align="center"><img width="600" height="256" alt="javascript00" src="http://localhost/img/test.png" title="javascript00"></p>

By use a simple regexp. It consists to delete the image class and add a <p align="center"> around only when the img class contain aligncenter 🙂

Thanks for help!
And merry christmas 🙂

Solution :

$result = preg_replace('#<img([^>]*?)?\s+class="[^"]*aligncenter[^"]*"\s*([^>]*?)>#', '<p align="center"><img$1 $2></p>', $data);

If you need this just for img tags, you can use this regexp:

  $data = '<img width="600" height="256" alt="javascript00" src="http://localhost/img/test.png" title="javascript00" class="aligncenter size-full wp-image-1973">';
  $result = preg_replace('#<img( [^>]*?)\s+class="[^"]*"\s*([^>]*?)>#', '<p align="center"><img $1$2></p>', $data);
  echo $result;
