php method to implement user registration login interface: 1. Create log.php main login interface; 2. Set register.php main registration interface; 3. Connect to the database through mysqli_connect and perform corresponding data operations.
The operating environment of this tutorial: Windows 7 system, PHP version 8.1, Dell G3 computer.
php How to implement user registration and login interface?
Simple implementation of PHP login and registration page (including database verification) (including database)
log.php (main login interface)
Because it is a simple page , the login page only performs database verification. In fact, email verification and verification code verification can also be added if conditions permit.

This I set up a random ID on the page. As long as I refresh the page, a new account will appear. However, since what I am doing is simple, I have not realized that the ID will not be repeated. If possible, you can implement it and send it to me for mutual communication. In addition, I have not set up repeated password verification. It is just a simple one. If you want, make it and send me a copy. Ha ha.
