I run a webserver using Xitami. When using SSI, your pages have to have the shtml extension, but I also run a php script in the same page, and it doesn't run if the extension is not .php. How can I run SSI with Php on the page? I'm trying to include a column of my page in an external file, so for all the subpages, I can refer to this file and I won't have to update every single page every time I want to change something in that column. Is there something in Php that lets you do this?
