Hello,

This gives me an error.

I want to remove ALL <h> tags, and also all words between h tags.

      $sitecontents = preg_replace('/<h[1-9]>.*?</h[1-9]>/', '', $sitecontents);

You're using / to note the beginning and end of the regexp, yet you then have a / inside.  That means PHP thinks "h[1-9]>/" are all modifiers, and not part of the regexp.  How about...

     $sitecontents = preg_replace('|<h[1-9]>.*?</h[1-9]>|', '', $sitecontents);

or just escape any / in your code, so you'd have: '/<h[1-9]>.*?<\/h[1-9]>/'
