I have an interesting problem. I'm using phpbb forum software and there is a file called viewtopic_body.html that I want to place a php script to rotate some text link ads under the post. I can't really rename the viewtopic_body.html file to a .php file because it's called throughout the software so changing that filename would probably not work. Any help would be greatly appreciated.
Just put <?php then insert your code here ?> just like that in you html file so that you will not rename it, you can ran php code by using that
