RE: [PHP] Anyway of knowing whether a integer is odd or even

It is generally faster to use bitwise operators... if ($theInt & 1) print "$theInt is odd"; else print "$theInt is even"; This is usually the case for most languages, like C or C++ or what have you. It's probably the same in PHP, since the & operator doesn't need to worry about returning the remainder, just the bits that are set in both $theInt and 1.
