[PHP] include option and calling only part of a file.

[Stephen of Blank Canvas]

Hi Everyone,
 
I have one file with several sections of code which I have so far
accessed using a good old fashioned - - if ($HTTP_GET_VARS['action'] ==
"Update") - - however I now want to include this code within some other
web pages, I thought I may be able to use the following code  - -
include("/modules.php?action=Update") - - however the code does not run.
Hoping someone can help me out on a way to overcome this.  I am running
IIS 5, and PHP 4.2.3
 
Thanks
 
Stephen
