Please see the man pages for array_shift and array_pop.

Both functions return the element they removed, not the
modified array.  So, $uri = array_shift($uri); is returning
an empty string, the first element of the array.

Let's say I have this string: 
/FAQ/ 
(a URI, actually) 
An explode action (delim is /)with a resulting count of the array
reveals 3 elements. 
After an array_shift or array_pop, the count goes to 1. 3-1=1?

$uri =
strtolower(preg_replace("/[^a-zA-Z0-9\/]/","",$HTTP_SERVER_VARS["REQUEST_URI"]));
$uri = explode("/", $uri); // make it an array
echo count($uri);
$uri = array_shift($uri); // delete first value which is always empty
echo count($uri);
