Hi.. I'm trying to make a PHP code that do the following :
Inserts the server time to the database (When login). and then insert it again (When logout). Now I want to compare the two values to know the defference between them by minutes.. so for example : if the defference was 2880 minutes then update a value in the database (Value in database + 1).. and every 2880 minutes I want to add "1" to the value.. This for lessons in my project.. the lessons must be updated every 2880 minutes.. but not automatically.. I mean the user can login for 60 minutes for example and then after 10 days he can login again and see the same lesson.. so every 2880 minutes the user stay in the program.. the lesson will be updated.. I tried to make it but everytime wrong. I hope you got me well.. Waiting your help and thanks in advance.. Best regards..
