That's because $_SERVER["QUERY_STRI NG"] is *always* set, regardless of
whether there's a query string or not. You might want to compare it to an
empty string, or check its length. Checking whether it's set or not does
not check the content at all...

So, the query_string just contains the URL that is requested? Could I
just see if the query_string contains a question mark and then send the
404 if a question mark is found?

No, $_SERVER["QUERY_STRI NG"] is empty when there is no query string. If
there is a query string, say the page is:

http://somesite.com/?something

then $_SERVER["QUERY_STRI NG"]=="something" . Check to see if the string is
empty, and if it is empty, then you're OK. If it's not empty, then a query
string has been passed.

Just do this:

if ($_SERVER["QUERY_STRI NG"]=="") {
// OK
} else {
// Query string present

You can also use the empty() function, which upon reading has been quicker
for some people than a straight comparison, not that comparisons are
notoriously lenghthy in their execution, but even so... ;)

Not true. With apache, QUERY_STRING will always be set; however, with
other web server software (ie. MS IIS) it will never be set unless you
have done so yourself.

Therefore, to be more portable, you may want to do something more like this:

if(isset($_GET) && is_array($_GET) && count($_GET)){
header("HTTP/1.0 404 Not Found");
echo <<< HTML
<html>
<head>
<title>404 Not Found</title>
</head>
<body>
<h1>Not Found</h1>
The requested URL was not found on this server.
</body>
</html>
HTML;
exit;
}

Incorrect. I tested it with Apache and IIS. BOTH have
$_SERVER["QUERY_STRI NG"] set regardless of whether a query string is present
or not.

I don't want to sound rude, but that's ridiculous. Just check to see if
$_SERVER["QUERY_STRI NG"] is a non-empty string. If it is, then hey-presto,
you're set. You don't need to call isset, is_array and count all in one go.

I turned off a module in our engine, and you are correct - IIS won't set
QUERY_STRING unless prompted to. Regardless, it still doesn't merit calling
isset, is_array, and count just to check whether a string is empty or not.

And not to mention your method only works if the query string is actually a
string of get parameters. If you pass just a string (as in his example),
the $_GET array is empty....

Just because your IIS server has it does not mean that is the default.
My install (and every other install that I have used) does not *ever*
have it set. My version is (as reported by $_SERVER['SERVER_SOFTWAR E'])
"Microsoft-IIS/5.1"

And then when you install to another server like Netscape? Zues? AOL?
Roxen? thttpd? The list goes on. You cannot *expect* a server to have
$_SERVER['QUERY_STRING'] set in all cases.
