preg-replace-callback

I have the following HTML statement [otsection]Wallpapers[/otsection] WALLPAPERS GO HERE [otsection]Videos[/otsection] VIDEOS GO HERE What I am trying to do is replace the [otsection] tags with an html div. The catch is I want to increment the id of the div from 1->2->3, etc.. So for example, the above statement should be translated to <div class="otsection" id="1">Wallpapers</div> WALLPAPERS GO HERE <div class="otsection" id="2">Videos</div> VIDEOS GO HERE As far as I can research, the best way to do this is via a preg_replace_callback to increment the id variable between each replacement.

You can use an anonymous function to pass the matches to your function: $result = preg_replace_callback( "/
