   For some reason or another I can't seem to access (just returns blank) $_SERVER variables to use with my stats system - it's only been happening since I started using wordpress, and I've made sure to clear any rewrites/etc out of my .htaccess and the httpd.conf itself. WordPress appears to be doing something with those variables (with varying things like the REMOTE_ADDR being available depending on where I require() the stats update code (which basically just tosses up another row in a mysql table.

   Since I'm not really sure what wordpress is doing, I'm kind of at a standstill scratching my head and wondering what to do.

   This may have something to do with WordPress's deregistering globals. Are you trying to access them like $REMOTE_ADDR? That would do it. Try using the normal way of $_SERVER['REMOTE_ADDR'] ...

   Also, you could try adding print_r($_SERVER) and seeing if there's any data there.

   Cheers

   I tried both $remote_addr and $_server['remote_addr'] - I'll try print_r and see what happens.

   This is the result: Looks like script URI no longer exists, along with a few other things. It's enough to work with, so thanks a ton, but I have to say it's odd that some of the variables are being completely erased.

   By the way, thanks a TON for showing me the print_r function.

   Remember, the $_SERVER global must be in ALL CAPS. And so do it's children like REMOTE_ADDR. Saying $_SERVER['remote_addr'] will turn up nothing

   Aye, that print_r() is a handy one. There's also var_dump(), but I usually find that you can get the info needed from print_r.

   Also, when I'm debugging, I've got this little function called echo_r(). It does the same thing as print_r() except it wraps it in <pre> tags.

   function echo_r($array) {
echo "<pre>";
print_r($array);
echo "</pre>";
}

   That allows me to see the array nice and formatted.

   Cheers

   I have a similar issue to this ... I have my print_r within a post using RunPHP.

   In my case i can see the output of the print_r shows that query_string is null even though my URI that i called the page with includes a query string. lots of the other values are being returned.

   My URI: http://localhost/wordpress/blog/category/sidebar/register/?var=value

   result of the print_r:

   Array

   [REQUEST_TIME] => 1160425108
   [argv] => Array
   (
   )

   [argc] => 0
   )

   in the header.php in my theme, i can see the var=value but in the page template page.php, the value is cleared.

   suggestions appreciateed. thanks
