Help using tar through php

[nigel.t@by.uk]

I'm trying to tar some files with PHP but can't get it to work.
From a linux command line I can use

>tar -cvzf myfile.tgz /home/

and it runs down the home tree creating the archive,
but if I put this into a php file as:

<?php
exec("/bin/tar -cvzf myfile.tgz /home/",$arrayout,$re turnval);
?>

All I get is returnval = 2
I've tried using system and passthru with the same result.
I can't see anything there that needs escaping.
I can't find any reference to a return value of 2 and arrayout
doesnt contain any help.
I'm out of ideas.

can anyone tell me how to do this please?
thank you

Append this:

for ($i = 0; $i < count($arrayout ); $i++) {
echo $arrayout[$i] . "\n";
}

and see what the command output is.
