Following is simple method to generate specific length verification code. Length can be specified, by default, it generates 4 digit code.

function get_sms_token($length = 4) {

    return rand(
        ((int) str_pad(1, $length, 0, STR_PAD_RIGHT)),
        ((int) str_pad(9, $length, 9, STR_PAD_RIGHT))
    );
}

echo get_sms_token(6);
