A simple helper to assist with writing MCollective actions in PHP.

Given an action as below:

action "echo" do
   validate :message, String

   implemented_by "/tmp/echo.php"
end

The following PHP script will implement the echo action externally replying with message and timestamp

<?php
    require("mcollective_action.php");

    $mc = new MCollectiveAction();
    $mc->message = $mc->data["message"];
    $mc->timestamp = strftime("%c");
    $mc->info("some text to info log on the server");
?>

Calling it with mco rpc results in:

$ mco rpc test echo message="hello world"
