Hi there all.
I try to create and attatch to a screen session via php.
When I type

Code:

screen -q

in the terminal it creates a new screen, but when i try to do it via php with

Code:

system("screen -q")

or shell_exec("screen -q"), it fails and tells me this : "Must be connected to a terminal".

Is it possible to be done ?

Thank you.

Yes, it is. But you must be connected to a terminal. This is an important security precaution.

screen is an interactive program which requires a tty. Although php
can be run interactively, I'll bet you're not using it that way.

If you are trying to run commands interactively without using a tty,
look at expect. You can use it to create an interactive connection
from within a script.

Thanks a lot @carltm. That is exactly what I need.
