PHP Cli key event listener function

I am making php cli application in which I need Key Event listener

let's say this is my code Task To do

for($i=0;$i<=n;$i++){
    $message->send($user[$i]);
}

Once I'm done with sending messages, I will have to keep connection alive with following code to receive delivery receipts.

I use $command = fopen ("php://stdin","r"); to receive user commands.

while(true){
    $connection->refresh();
}

Connection is automatically kept alive during any activities but on idle i have to keep above loop running.

How can I run the event on pressing any key which will make this event break and execute some function?

PHP is not developed, to handle this kind of problems. The Magic Word would be Thread

The Cleanest way, I can Imagine, is taking a look into the Extension PThreads. With it, you can do Threads like in other Language:

class AsyncOperation extends Thread {
  public function __construct($arg){
    $this->arg = $arg;
  }

  public function run(){
    if($this->arg){
      printf("Hello %s\n", $this->arg);
    }
  }
}
$thread = new AsyncOperation("World");
if($thread->start())
  $thread->join();

The other way would be to do tasks via a queue in a different script. There are some Queue Server out there, but it can be done simple calling shell_execute your Queue Script via PHP.exe. On Linux you need something like ...script.php > /dev/null 2>/dev/null &, Windows start /B php..., to stop waiting on Script is finished.
