Introduction and ideas of registration function in PHP development

As long as the website requires login, you need to register first. Only if you have an account, you can log in.

For example, our QQ chat, Aliwangwang, recruitment website, games, etc.

How can this be achieved? Let’s introduce the implementation idea below:

Registration means writing the account number and password into the background database, and then retrieving data from the database when logging in. Only when the account number and password are correct at the same time can the login be successful, otherwise it will fail.

Then you first need to build a database to store the data written when users register (will be introduced in detail in the next chapter).
