Hello, I recently came across this great site and discussion board.
I am looking to create a notifier of sorts. I plan on going about this by creating a php script that scans a forum page (for example one of these forums). The php script would be in a constantly open window that refreshes itself every few minutes. The script would be looking for a new post, and if it finds a new post then notify me with a bell sound.
I was thinking of doing this by have two variables that store all of the html on the page into one. When the page refreshes, store the html into the other and check for equivalence. If they are not equivalent, then play the sound, and store the second variable as the first and repeat. If they are equal do nothing.
While I feel that this would work, it seems rather excessive to me. Any thoughts on how I could do this more efficiently?
