We're currently using an AS/400 system. I was asked by my boss to to look for a way to call RPG programs from PHP on our Apache server. The only solution I've come up with was installing Zend server to AS/400 and using the i5 PHP API Toolkit. Since I don't fully understand AS/400, I haven't tried it out yet.
We can connect to the database / read and write from PHP. But I'm just trying to figure out a way to call a RPG program on our system from PHP code and send parameters, retrieve output. Thank you!
