Question :
========
I would like to write a generic PHP script that can handle data coming
from any form. How do I know which POST method variables are available?
You need to compile PHP with the "--enable-track-vars" configure switch.
This creates three associative arrays. $HTTP_GET_VARS, $HTTP_POST_VARS
and $HTTP_COOKIE_VARS. So, to write a generic script to handle POST
method variables you would need something similar to the following:
while (list($var, $value) = each($HTTP_POST_VARS)) {
echo "$var = $value<br>n";
}
you can turn --enable-track-vars on, or even turn it on, on a
per-script basis by putting:
<?php_track_vars?>
as the very first line of your file.
