PHP registration page mobile phone verification code is stored in the database

To put it simply, mobile phone verification and mobile phone registration are similar.

Mobile phone verification:

First you generate a string in the php code, which can be saved in the session, and then send this string through the SMS service (this step requires Buy, find an agent, provided you obtain the user's correct mobile phone number) and send it to the user, and then provide an input box for the user to enter the verification code received and compare it with the session.

Mobile phone registration:

The previous parts are the same as above. The extra step is to save the information into the user database after successful verification. At most, the user is allowed to re-register before saving. Enter some other user information.

The above verification code can be expanded. For example, the validity time can be set directly in the session, and the expiration and invalidation limit is enough.

You can go to the backer platform to have a look, the stuff in it is pretty good
