I have an interactive menu script written in bash and I would like use PHP to open the interactive bash menu in a browser.

sim, SIM - Software phrase input method
DESCRIPTION
The phrase input method is an input method that is commonly used in a Chinese environment. The software phrase input method (SIM) is a a
mechanism supported by the Asian tty driver, atty and the simd daemon through the utx facility (see atty(7), simd(8), and utx(7)).
The stty command activates the software phrase input method, while the phrase utility creates and manages the phrase database (see stty(1)
and phrase(1)).
Changes to the phrase database may not be reflected in SIM sessions that were started before the changes were made. Therefore, users have
to stop and then restart SIM sessions using the stty command to have access to the changed phrase database.
