Generate a random number or string in PHP.

        // Generate unique code

        function generateUniqueCode()

        {

                $nRandom = generateRandomNum(1, 50000);

                $nMicro = getMicroTime();

                return ($nRandom + $nMicro);

        }

        // Generate a random number

        function generateRandomNum($Min, $Max)

        {

                mt_srand((double) microtime() * 1000000);

                return mt_rand($Min, $Max);

        }

        // Generates a code string

        function generateCodeString($strKey = "")

        {

                return strtoupper(sha1($strKey . generateUniqueCode()));

        }
