PHP Include

[MasterSlowPoke]

I include the variable portion of my site, and have the static portions remain. I only use one .PHP. A while back, someone on some forum said my code was inefficent, but didn't explain why. I'm rebuiling my site, and would like to see how I could soup it up. This is my current code.

the top banner, layout, ect
<?php 
   if(!empty($HTTP_GET_VARS[page]) and file_exists("./$HTTP_GET_VARS[page].inc")) 
      { include("./$HTTP_GET_VARS[page].inc"); } 
   elseif(!empty($HTTP_GET_VARS[album]) and file_exists("photos/$HTTP_GET_VARS[album].inc")) 
      { include("photos/$HTTP_GET_VARS[album].inc"); } 
   else { 
       include("./main.inc"); 
   } 
?> 
the footer, </body> ect

could use ['page']

($HTTP_GET_VARS[page])

how about $_post ? http_get_vers is in a older version of PHP, look in the manual for the new functions (they still work tho)
