PHP calling RPG program

Can anyone offer any examples, good websites or books on how to call RPG
programs from within a PHP script running on the iSeries using PASE?

I am trying to call an RPG program with parameters from within PHP.  We
have a web site running .NET but need to access our images on the iSeries
that have been scanned and placed into the IFS.  The images have been
scanned in as a .TIF and we are running an RPG program to convert this
images from a .TIF to .PDF and display on web using PHP/RPG.

Thanks in advance.
