You probably want to use proc_open or popen to communicate with IDL
directly. Here's an example I found interfacing to GNUPlot:
http://celeste.cn/PHP-GNUPlot/
The issue will be starting and restarting IDL continuously for each
request, which, if they are frequent, will be painful.

I can compile and run the file on the command line but I cannot figure
out a way to run the program using php. I am working on php and have
been trying to use the php shell commands to execute the .pro file but
it doesnt seem to work.
Thanks for the help.

Hi Pranav,
I think you might want something called a batch file. This is a file
containing a series of commands rather than a typical idl program which
starts with PRO or FUNCTION. You can call this from the shell with the
following:
idl batch.pro
The batch file can compile and run normal IDL programs... suitable
contents for batch.pro could be
.r myprog.pro
myprog
and make myprog.pro a standard idl program (or function)
cheers,
Ben

In PHP the statement we use to execute an IDL script (the name of which is held
in $idl_input) is:
system("idl < ".$idl_input." 2>&1",$return);
or
exec("idl < ".$idl_input." 2>&1",$output,$return);
