This program is a relatively simple small php+mysql registration and login system independently designed by Summer Blog. The version number is V0.2. PHP submits the registered user form and sends it to the mysql database. Friends who often do websites have this small registration system. It’s much more convenient. 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 user passwords are encrypted with md5. The functions are relatively complete and can be used on this basis. It is better to carry out secondary development to suit the website application. The main functions are: (1), user registration function. (2), user login modification function. (3), Administrator login management. (4), Zhengda expression verification. (5), md5 password encryption. Backend management: index.php, which is also the homepage file. Just enter the administrator account: admin and password: admin. For member users' own management, they need to enter their registered username and password for management. The default is enough here.
