run command after process initialization

[raven_black]

hello,

I have this problem in running a specific command after using shell_exec or exec to execute a certain process.

The process I am running is unimrcpclient, after initialization, it expects some command to be entered in order to communicate with the mrcp server. however, passing the command as an attribute is not an option. Is there a way in PHP to execute a process, wait for initialization and then pass the command automatically?

thank you.

this can work if the program is expecting only a limited amount of interaction

$command = "/path/program < /path/command.txt";

command.txt contains the line you need to pass to the program

Thank you, it worked and ran the command successfully.. however, now that it's running, how can i capture the output (result) of the command execution? i tried using & at the end of the above command but it did not work.
