This fully functional small php+mysql registration system is a relatively simple small php+mysql registration and login system independently designed by Summer Blog. The version number is V0.1. PHP submits the registration user form and sends it to the mysql database. It is often used for websites. Friends, it is much more convenient to have this small registration system. Field names can be added and deleted freely. Regular expressions are used for data verification when submitting. The source code is relatively streamlined and independent account management can be carried out. Registered users are encrypted with md5, and the functions are pretty good. It is relatively complete and can be used for secondary development on this basis to suit website applications. There are 6 files in this program: index.php login registration page config.php mysql database configuration page style.css page CSS style admin_index.php Administrator login user page member.php member view and modify information page regi.sql mysql database file
