Hi all,

I'm having the same problem as Jim Poserina. Richard pointed out some
things to try. Here's my story.

We installed Fedora 3 on a new box. Then we installed Apache 2 and
PHP 4.3.9 from the RPMs that came on the CDs. Pretty much everything
works as expected, except the exec() functions do not work in the web
server. There is no error message displayed in the browser or in the
error_log of apache. Here's the script:

<?php
$x = exec("/bin/pwd", $y, $z);
echo "<br>x is "; var_dump( $x );
echo "<br>y is "; var_dump( $y );
echo "<br>z is "; var_dump( $z );
?>

Here is the output:

x is string(0) ""
y is array(0) { }
z is int(127)

If I run the php interpreter from the command line, exec() does work
ok. I can turn safe mode on and define a safe_mode_exec_dir and copy
/bin/pwd to it and then run that and the command line interpreter
honors that setting ok. The web page result doesn't change though. No
error message, no output. Just the 127 (-1?)

So, what do I have to change in my setup to get the exec functions to
work in the web server?

Thanks,

Bill Rausch
