Basic PHP script modification including scraping

I need somebody to make some very basic modifications to my PHP script. Currently, I have a form with 3 elements all contained on one page. I want it separating into 3 separate pages so that it is easier to use. Example: Step 1 -> Step 2 -> Step 3 Secondly, my website gives a user a point when they download a file and enter a code. At the moment no matter what the file size is, it still only issues 1 point. The files are hosted externally on Hotfile, FileServe and Uploading. I want the script modifying so that it will scrape the file size from these website and issue the user with different points depending on the file size. For example if its 1 to 50MB, 1 point, 50 to 250, 2 points etc etc. Message me if you need anything clarifying.
