R help - Apr 2004 - R apache and PHP

I've developed a web application in PHP and R

my script is


<?php

...
exec("R CMD BATCH --silent /home/marcello/R_in/myfile.bat  
/home/marcello/R_out/myfile.out");

...

?>

This script execute in R batch mode and write the myfile.out.

On Win2000 the similar script is ok, but on linux I've a problem.

I suppose is a permession problem because the same script on shell run fine
and on Zend debugger (my IDE for php) is also ok.
In this case the owner is "marcello" , if I run the script by browser 
the owner is "apache".

I've  overwritted all the ownerships of R directory and bin to apache 
user but not work.

If a run
exec("ls > mydir.txt"); is ok (is not a PHP general problem!)

Someone can help me?

Thanks
(and excuse my for my poor english)

We need to know what kind of error message you are getting before we can be
much help.

Apache may not aware the PATH to R, try 'exec("/pathToR/R CMD
...")'.
In addition, apache and R should be in the same physical driver.
