And why not just return that directly, rather than assigning it to an intermediate variable that you're not using for anything else? Actually, I'd probably ask the same about all your intermediate results -- I'd probably have written this whole thing as a single statement, thus: return end(explode("/", $_SERVER['PHP_SELF'])); Cheers!
