There is no reason to use eval. It's evil.

I don't see anyone using eval here.

I'd suggest it's probably a permissions problem. Anything in your error logs?

Re: exec returns -1

The echo actually suceeds, so there are no errors associated with
running this command or loading the page.

Re: exec returns -1

ok, not sure what you mean about eval since its nowhere in the code I
posted. However this example is similar to a function that is failing
when I try to enable Imagemagick in gallery 2.2 & 2.1. Since the
gallery folks do not support Iplanet I'm more or less left to my own
devices to breakdown the code and find the core problem, which is what
I've done here. Unfortunately I've broken it down as far as I can for
now...hence the post here.

Where is the executable for the "echo" command? (answer for both
setups). Is the directory the executable for the "echo" command
is in listed in $PATH (answer for both setups)? Is safe mode on,
and if so, is the executable for "echo" present in a directory
listed in safe_mode_exec_ dir (answer for both setups)?

Note that I don't see anything in the description of exec() that
says you can use shell builtin commands (just as you can't on the
C exec() function).

Re: exec returns -1

Checked and the 'echo' binary is in /bin/echo. The PATH for a user
ssh'd in and that of a script being executed by the browser both
include "/bin", so there is no issue from that perspective. This can
also be confirmed that it is working from the output below. Since it
sucessfully produces the string "hello world". The echo command is
working, however the result code which exec is setting is always set to
-1 when the script is invoked by the webserver. This is true even if
the command you are trying to run is invalid or does not exist. If I
run the same script with an invalid command from the command line, the
exec function in this scenario gives a status of 127.

This is the output from hitting this script on a webserver with a
browser:
############### ########
Output: hello world

command: echo "hello world"
results: Array
status: -1
############### ########

This is the output from hitting this script through an ssh session and
running "php go.php"
############### ########
Output: hello world co mmand: echo "hello world" results:
Array status: 0 
############### ########

Re: exec returns -1

Does php need to be compiled with a special option for use on
iplanet/sunone webservers on linux for the exec function to work
properly?

They may have safe_mode on or exec() disabled. What does phpinfo() say?

I think they are off, but you can see the output here:

Ah, I missed the fact you're using Sun.

It has some security features in it, also. I've never used it, but I've heard
of people who have problems with it.

Maybe someone familiar with it can hop in here.
