Question

See Anonymous function below, I do not want go to next for loop iteration until $Connected is 0

It did not work how it should be… what is the solution to fix this?

 $Client = new Client();

for ($i = 1; $i <= 5; $i++) {

 $result = $Client->Action(rand(1,1000));

 if ($result->isSuccess()) {
     $Connected = 1;
  }

  // Stay in the loop until 'HangupEvent' received
  while ($Connected) {
    $Client->EventListener(function (EventMessage $event) {
        if ($event instanceof HangupEvent) {
            // Received Hangup Event - let terminate this while loop ..
            $Connected = 0;
         }
    });

   // If  $Connected = 0; then go to next `for` loop iteration
  }

}

You need to pass the $Connected variable to your function with use

$Client->EventListener(function (EventMessage $event) use (&$Connected) {
    if ($event instanceof HangupEvent) {
        // Received Hangup Event - let terminate this while loop ..
        $Connected = 0;
     }
});
