okay i have a site with the main page index.php with a blank section, then when i click link
<a href="index.php?id=1">lala</a>

id=1 would open the same index.php but with the info it calls for from 1, 2, 3, ect ect.

what code would it be to use, i thought it would be
<?php include ("$id.txt"); ?>
