Regular expression to remove <p> tags from around img elements

Question

I am looking for a regex to convert all

<p><img /></p> 

to simply

<img />

The img tags will be fully populated such as

<img src="/file.jpg" width="1" height="2" />

Thank you for your input!

Answer 1

This will work if there is nothing else on the line except the three tags. Let me know if you want it explained further.

$str = "<p><img src=\"/file.jpg\" width=\"1\" height=\"2\" /></p>"
$replaced = preg_replace ( "/<p[^>]*?>(<img[^>]+>)<\/p>/" , "$1" , $str )
