exec() and zip

[Ike]

I have zip.exe in my PATH on a windows XP box. Additionally, I have a script
which, if I execute locally with

php myfile.php

it runs fine. However, when I call myfile.php remotely with a web browser,
it canot seem to find zip.exe. Below are the releveant code snippets. TIA,
Ike

exec( "zip -mj \backups\temp\c ookbook.zip \backups\temp\c ookbook.sql 2>&1",
$output, $res );
if( $res 0 ) {
error( true,"COMPRESSI ON FAILED\n".implo de( "\n", $output));

COMPRESSION FAILED
The system cannot execute the specified program.

Ok, zip has been run since the system cannot produce the message
COMPRESSION FAILED from itself, so you need to check the arguments.

Rudi,
Do you mean the arguments to exec ? Why then would this run in
localmode? -Ike

Do you mean the arguments to exec?

Nope, but to "zip.exe"

Why then would this run in localmode? -Ike

Perhaps you need to set the current working directory properly
or use absolute paths, i.e. those who begin with a drive letter
like c:\some\directo ry\cookook...

I am sure, this will solve it!

Does the userid the web server is running under have access to zip?
Check your security settings.

Hmm, it's apache 1.3.x for Windows -- I can't really tell (there is no
..htaccss in the directory where zip.exe is, which is on the windows path).
What if I put it in c:\backup and called it explicitly like c:\backup\zip ?

I've used Winzip on my WAMP setup - Windows XP (and then switched to
7zip - much easier).

To get zip to work from an exec call, I had to open the Services window
(Run - services.msc) - select Apache - click on Properties - go to the
Log On tab and then check "allow service to interact with the desktop."
(I've been flamed for admitting to doing that, too. ?)

After learning more, I downloaded 7-zip (free), which comes with a very
nice command line interface and I switched to using that. It works much
nicer (and it can create .zip format).

Any idea why you got flamed for that? I'm just wondering if/what kind of
security risk this would have created. Thanks, Ike

No security risk, I was just told that it was "bad form" (to put it
mildly) to run a GUI app from a web request. And the flamers were
confused about how I was using the Php script.

If all you want to do is zip a file, I suggest you try 7-zip (unless you
have the command line version of WinZip).
