that's the bit I'm stuck on
It needs to have the IP address of the visitor and a timestamp,
then it needs to delete the line that contains a timestamp which has been outdated by a minute.
So, I need to make a text file like this:
I was thinking of using the unix timestamp.
How can I search the file and take out the lines of the outdated visitors.
Anyway! I think I'll just wait for the SQL!
