Database management project in PHP. SQL requests use prepare() and execute() to secure the application by preventing SQL injections attacks. The front end is done in Boostrap with a bit of custom CSS. The application registers users if they do not already exist, displays them and allows their modification. The forms send data in POST and retrieves errors in GET using query string parameters. For the exercise the passwords are hashed in md5 but it is better to use something like bcrypt in production.
