Hello
My PHP script executes many bash/cmd commands.
Functions like "exec()" or "system()" cause that new bash/cmd session
is started,
the command is executed and the session is closed. Unfortunately
it is very slow process so I would like to increase performance and
open one bash/cmd session on the begin of my script and execute
the commands such as in normal system opened bash/cmd window and close
it
at the end of my PHP script.
Does anybody know whether and (if yes) how can I do that?
PS. I need the retrieve informations from previous command before
executing next command because next command is strongly dependent on
the
results from previous command.
Best regards
Melmack

Melmack,
You might be able to open the command shell with proc_open() and
communicate through the pipes.
I've never tried it in PHP, but done similar in C before.

I would write a bash script and just execute that from within PHP. If
you're using so many commands that performance is becoming an issue,
I'd recommend that you try that. Bash scripting is terribly easy to
learn if you don't already know how. Even if you did find an
alternative in PHP, I don't think it would be as efficient as
executing a single script.

Can't do it with a bash script unless you're willing to do all the work
in the script.

Perhaps you've misunderstood me: doing all the work in the bash script
was what I had suggested, in fact. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |
