server erro file, what's this?

I get tons of these everyday. It almost looks like someone is trying to find a file that doesn't exist? Has anyone else noticed thios about their gamezone setup?

Here's the file.

1.<?php
2.
3.
4.        define('BX_SECURITY_EXCEPTIONS', true);
        $aBxSecurityExceptions = array(
            'POST.gname',
            'REQUEST.gname',
            'POST.gscore',
            'REQUEST.gscore',);


12. $sGetDo = $_GET['do'];

/* OLD

if(!empty($sGetDo)){
    if($sGetDo == "newscore"){
*/


// NEW
22. if($_GET['do']=="verifyscore") {
print "&randchar=1&randchar2=2&savescore=1&blah=OK";
die();

Is it looking for a  score that doesn't exist maybe?

It's more likely the result of google or other crawler or even a person calling the url with out the parameter it is trying to get from the $_GET.

Without seeing more of the code i can't tell you exactly how to fix it. But it would be something like this.

if(isset($_GET['do'])) {
$sGetDo = $_GET['do'];
} else {
$sGetDo = '';
}

That check using isset would make sure that something is there before it tries to retrieve it and if nothing is there sets the variable as null(empty) which should get rid of the warnings.

Thanks. That makes total sense.

Now, when are you going to fix this stupid signature line?

Edited my previous posts. Missed a )   Syntax error.

Now how on earth am i going to fix the boonex.com sig line?

No .... Not theirs, MINE!

The signature line here is weak as it is on my site. Would like to be able to allow my users to spiff up thjeir signature lines, including images (banners and such). Was hopin you'd see it like i do and create a little mod to fix it....
