Another minor performance tip to add to this is to use $p in your
conditional statements rather than $_GET['p']. Of course, you should
filter this data also, but try something like this:
if ($_GET['p'] is valid data)
{
$p = $_GET['p'];
}
When you use $p in the rest of the script, you save PHP the small
discovery time required for $_GET['p']. If you have many conditional
statements, this minor improvement can be amplified slightly, and if you
have many users (a few million a day, for example), this improvement is
further amplified.
Hope that helps.
