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.
