exec problem ?!?

[rain]

Hello,
I am having some serious problems executing a command on my redhat linux
machine using exec, shell_exec, or any variants thereof.

I have a string saved into a variable like:

$mystring = "/usr/local/bin/lmc -e add /music/whatever.mp3";

Then I try to execute w/ something like:

$last_line = exec($mystring) ;
echo "{$last_lin e}";

This does absolutely nothing but when I run the same thing from the
command line it works fine. I also have made sure that it is not running
in safety_mode. The current user is nobody, but the program is accessable
to everyone. Any thoughts or places where I need ot provide more info?
Any suggestions to troubleshoot?

Brian

PS: this is driving me bonkers.

I've tried w/ no success: system(), passthru(), fpassthru(), exec(), and
shell_exec().

Interestingly though I can't get any response from any of these commands.
Even when I execute a system command w/ one of the above funtions which
should return an error I receive nothin on a variable like $temp where the
code is:

$temp = exec("Code that will produce an error");

Any other thoughts

Thanks!

What return code are you getting? (See the third parameter to exec()
in the manual).
