Hmmm.

>From the manual...

"string exec(string command, string [array], int [return_var]);

exec() executes the given command, however it does not output anything."

<snip>

"If the array argument is present, then the specified array will be filled
with every line of output from the command."

<snip>

So... echo exec("pwd") would output nothing, as stated. However, if I
execute the following script in the /home/httpd/html directory:

<?php

Exec("pwd",$result);
echo "$result[0]\n";

?>

the output is "/home/httpd/html", as expected.

I may be hallucinating, but I've never known exec() to
output anything, unless the output is dumped to the array
specified in the second argument.

The behaviour is the same I agree. I believe it's the expected
behaviour.
