Resetting password

We can reset a user's password by directly modifying the MySQL database table called users_table. More specifically, we delete that user's information from users_table so that the user could sign up again. Suppose the user's student number is 201131129138.

To do so, LRR administrator logs in to MySQL using the following command: mysql -u username -p. Type the correct password to access the MySQL database.

After that, issue the following commands in the mysql prompt.

  • use lrr;

  • delete from users_table where Student_ID="201131129138";

The first one uses a database called lrr in MySQL. The second one deletes a record from users_table where the student number is 201131129138.

Increasing session duration

By default, the session duration in PHP is set to 1,440 seconds (24 minutes). However, this is not convenient in most software systems. Therefore, we may need to increase the duration to allow users to have more session time. To increase the session duration, we need to edit the variable session.gc_maxlifetime in php.ini. We can increase its default value to whatever we want (e.g., 7200). On Ubuntu, the file is located at /etc/php/7.2/apache2/php.ini. On XAMPP, the file is located at /xampp/php/php.ini.
