if you want to run a php program in your terminal you need to add an argument I think it is -r but quickly read the manual
-> man php

I just answered another question that probably overlaps a great deal with yours. As in the other question, this is almost certainly just what you suggest here: a question of the fact that the "user" running the web server is not root (or whoever) so you need to grant limited privs to the web server. The discussion below "Now here comes the warning" in that post should be the answer here too.

You may be root, but when you run a script from a browser, root is not (or at least should not be) running the script --- the web server user (probably www or httpd) is running the script on your behalf. To whom did you grant permission?

At least 80% of the time when one user can run something and another cannot the problem is some kind of permission problem. Virtually all the rest of the time, it is an environment problem. The first question is "who is your web server user?" For example:

[root@foo ~]# ps -ef | grep httpd
www       2248     1  0 Jan04 ?        00:00:00 /usr/bin/perl /home/httpd/perl/bar

shows that www is the user that actually runs the webserver on host "foo". So, does www have permission to run your script. If you are root, do:

[root@foo ~]# su - www

(don't forget the "-" in that command!!!) and then try to run the script. Does it run properly? If yes, then we'll have to come up with another hypothesis, but I would be very surprised if it does. You are likely to get some kind of informative error message if it does not.

Let us know what happens.
