Fix twitter application (just 1 page)

I have a twitter application that needs 1 php page fixed. The twitter app installs to user and allows for further posting via a php file ran in cron. The problem is that the script only runs once, and if there is a lot of tokens it times out the server. What i need is: 1. For the poster to be able to post multiple times. 2. Break up the operation so it only posts 100 tokens, then splits up to a second link (to post another 100, and another... etc...etc... this is so the server does not time out) 3. The [login to view URL] must have a visible output of what it's doing on the page. This is a quick job, just 1 page of code and the script is already finished and working (except for the small bug)
