$_SERVER['QUERY_STRING'] is empty in our 404-handling script, which is displayed when the user's URL is not found.  The query string appears correctly in REQUEST_URI, so the data is there, it's just not getting into the QUERY_STRING var.

Here are some dumps of the $_SERVER array, for an existing script, and a bad URL that displays the 404 script:

This is how Apache behaves. It doesn't set QUERY_STRING when
page is not found as it's redirected.

You can test this with putting phpinfo() into your 404 script. Search for "REDIRECT_QUERY_STRING" in the "Apache Environment" section..

(it's also in _SERVER var)

Am working on this.  There are several REDIRECT_* predefined vars to use.

This is actually part of an open phpdoc feature request made here:

http://bugs.php.net/7741

Not every single possible predefined variable is documented, that's quite a job.  When/if it does happen, this information will exist within it :)
