It seems logical that if we support increment we should support decrement. My proposal: 1) Support decrementing letters - or - 2) Throw a notice explaining that decrementing is not supported so developers quickly know they can't do that One hiccup. I imagine maybe the reason we don't support decrementing is because what would happen if you tried to decrement 'A'. In that case I would suggest either returning NULL or throwing a notice. Thanks for the input Chris London Hello, Does anybody understand the rules behind the string incrementation? What's the explanation of following behaviour? '$x="ZZ";$x++;var_dump($x);' returns string(3) "AAA" '$x=" ZZ";$x++;var_dump($x);' returns string(3) " AA" see http://www.php.net/manual/en/language.operators.increment.php thanks Regards, Mateusz Kocielski
