[PHP] preg_replace & templating problem

programming
1

Hello, I am trying to implement a system where there is a content file, template file, and then a script that places the content of the content file into a certain variable of the template file. I have this working but have one problem.

    [u]The way it is set up is like this (extremely condensed):[/u]
     1.) open the template file and store the contents to a variable
    2.) open the content file and store the contents to a variable
    3.) use preg_replace to place the content into the template at a template variable {var}
    4.) echo the data
    
But when I try inluding another php file in content file *"[color=Navy]<?php include("anotherfile.php"); ?>[/color]"* the included file is just ignored and doesn't appear in the output. I tried using preg_replace in the main script that changes a template var *"inc"* to *"[color=Navy]<?php include(\"afile.php\"); ?>[/color]"* (Code Below). This didn't work: when I viewed the source of the output page it appeared as *"[color=Navy]<?php include("content/afile.php"); ?>[/color]"* but did not get processed.


        $var = preg_replace("/inc/","<?php include(\"content/afile.php\"); ?>",$inputcontent);
        

    Are there any ways of doing this? Any help will be greatly appreciated. [img]http://www.kirupa.com/forum/images/smilies/happy.gif[/img]
