I need a very simple PHP script with an even simpler GUI. It should do the following :
1. Take a URL in a text box.
2. Take a directory in another text box.
3. Download the file in step 1.
4. Split the file into parts of pre-defined size.
5. Save the split parts in the directory mentioned in step 2.
The download can be done through curl and the splitting can be done with the help of a pre-made package like [url removed, login to view] . I don't need a complex / fancy GUI or anything, just need someone to write the actual code since I don't have the time to do it myself. Please, no generic bids, they will be ignored on sight.
