I'm building a real time message system and used this http://www.sanwebe.com/2013/05/chat-using-websocket-php-socket/comment-page-1 tutorial as an example.
In my local PC it worked find. I have a shared server and hosting provider doesn't allow me to access shell command on my server.
Can anyone help me on this. Is there any way I can execute this shell command in a PHP file?
