title: Run and Receive a Command in screen via PHP
body: <p>I'm making a Minecraft control panel, but are sort of confused on how to send a command to each screen. I understand how to execute a command to a screen, but I don't understand to read the output.</p>
  
  <p>Ex. I have screen A and screen B. I want to execute something in screen A, and get the output, and then exit the screen.</p>
