Run and Receive a Command in screen via PHP

问题

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.

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.

Here's an easier solution: Use Websend bukkit plugin (Download&info) in both servers. PHP can simply execute commands and receive outputs when plugin is installed and php classes setted up, also this can be more complex than bash screen, and much easier to setup and use.

Here's an example use of this:

<?php
include_once 'Websend.php';

//Replace with bukkit server IP. To use a different port, change the constructor to new Websend(ip, port)
$ws = new Websend($ServerIP, $ServerPort); 

//Replace with password specified in Websend config file
$ws->connect("password");

$ws->doCommandAsConsole("give ".$PlayerName." 64 1");
$ws->disconnect();
?>

In this example the script item to a variable-definied player. You can execute a custom variable command with replacing $ws->doCommandAsConsole("give ".$PlayerName." 64 1");' to$ws->doCommandAsConsole("$_REQUEST['customCMD']"); where customCMD is a field in a GET or POST form.`

Don't actually need a plugin, but keep in mind using shell_exec could open a massive world of pain for you when it comes to security.

However, I was having a similar issue with implementing a control panel in drupal, I managed to run commands to a screen using the following code.

shell_exec("screen -S ScreenName -X stuff \"echo hello world\"'\n'");

You're welcome.
