When I view that file, on line 19, I see:

Well, that wouldn't address the issue of the code he gave on the
line reported, but I know what you mean, Richy. He's turning
$_SERVER['REQUEST_URI'] into an array with explode() if it contains a
forward-slash ("/").
What would be better in that case would be:
<?php
$data = isset($_SERVER['REQUEST_URI']) &&
strlen($_SERVER['REQUEST_URI']) > 0 ?
explode('/',$_SERVER['REQUEST_URI']) : $_SERVER['REQUEST_URI'];
if(is_array($data)) {
// Handle as appropriate.
}
?>
However, that's not the best option as:
1.) REQUEST_URI may not (though it should) have *any* forward
slashes in the URI passed to PHP by the HTTP server.
2.) It leaves too much other stuff to be done.
Instead, check out:
<?php
$data = basename($_SERVER['REQUEST_URI']);
echo $data; // In case you're not yet aware of what you'll receive
from the use of basename()
?>
