problem 1) prepare a php code that would do the following with the countdown timer:
Visitor 1 visits my web page where webpage is and they see a timer (30minutes).
Visitor 1 has now been on my web page for 10 minutes and now has 20 minutes before timer runs out.
When a new visitor #2 visits. When this visitor is on the website they would see the countdown timer however I want there timer to add 30minutes from the time left of visitor 1. This means visitor 2 countdown would be 50 minutes.
For each visitor that visits the web page add 30 minutes from whatever time is left from the previous visitor.
Also after timer reach 0 a hyperlink must appear.
