I'm looking for an innovative (read: free) way to scrape an AS/400 screen using PHP? Over time, we've had a number of programmers writing AS/400 applications and now I've been tasked with finding a way to make the screens they've developed available outside of AS/400. My first thought is to use PHP, since I'm not particularly fluent in C# or other languages that would probably make more sense. Anyone have any suggestions? Note, I am aware of Zend, but it is not free to use.
