It is generally recommended to explicitly declare the visibility for methods.

        $uuid = sprintf('%04x%04x%04x%03x4%04x%04x%04x%04x',

            mt_rand(0, 4095),  // 12 bits before the 0100 of (version) 4 for "time_hi_and_version"
            bindec(substr_replace(sprintf('%016b', mt_rand(0, 65535)), '01', 6, 2)),
            // 8 bits, the last two of which (positions 6 and 7) are 01, for "clk_seq_hi_res"
            // (hence, the 2nd hex digit after the 3rd hyphen can only be 1, 5, 9 or d)
            // 8 bits for "clk_seq_low"

        return $uuid;
