To create a new table:

CREATE TABLE `Captcha` IF NOT EXISTS {   `id`        INT,   `phone`     VARCHAR(15),   `code`      VARCHAR(15),   `status`    ENUM('Normal', 'Verified'),   `expire`    DATETIME);

Development A but do not know how to do the general is now used by others have done well (the price is also OK the most expensive should be 8 cents a bar) call someone else's interface client's no cookie SESSION can generate token mode or write a file form it
