sudo in php exec()

I don't know what the deal is here…

So I want to run an applescript: sudo osascript myscript.scpt

This works fine in the terminal, but not when I execute it via PHP's exec(); nothing happens. The console says

no tty present and no askpass program specified ; TTY=unknown ; …

I did my research, and it seems I'm missing the password for the sudo command. I tried a couple different ways to get around this, including:

• writing %admin ALL=(ALL) ALL in /etc/sudoers
• and proc_open() instead of exec()

none of which seem to be working, consequently driving me CrAzY!

So basically, is there a clear-cut way to get PHP to execute a simple terminal command?

EDIT: to clarify, myscript.scpt is a simple appleScript that changes the onscreen UI (for a larger project). In theory, simply osascript myscript.scpt should be enough, however the sudo is for some reason necessary to invoke some response from the system. If the sudo could be somehow eliminated, I don't think I would be having this permissions problem.

It sounds like you need to set up passwordless sudo. Try:

%admin ALL=(ALL) NOPASSWD: osascript myscript.scpt

Also comment out the following line (in /etc/sudoers via visudo), if it is there:

Defaults    requiretty

I think you can bring specific access to user and command with visudo something like this:

nobody ALL = NOPASSWD: /path/to/osascript myscript.scpt

and with php:

@exec("sudo /path/to/osascript myscript.scpt ");

supposing nobody user is running apache.
