Calling External PHP Script

Hi, Does anyone know a method of calling an external PHP script from a stadard .html page ? I have one server with no PHP support at all that contains most of my exisiting static pages, but I would like to try and update them over the next few weeks one at a time, to call a script from my other server which has PHP 4.3.1 running. I have tried various methods, but nothing appears to work for me. <script language="PHP" src="http://www.phpdomain.com/shownews.php?Category=Site"></script> Any help appreciated. Thanks Mr DragonFly
