php-amqplib: How to prevent infinite loading web page?

Question

I use a cloud service to handle RabbitMQ. The purpose is to send and receive messages from smart objects that use MQTT. All works but... A formPage.php on submit triggers a shellexec command that executes initRpc.php. In initRpc.php this infinite loop is used to receive messages but block every other functions even if declared before, like an header('location ...');

while (count($channel->callbacks)) 
     {
       try {
           $channel->wait(null, false, $timeout);
           }
       catch (AMQPTimeoutException $e) {
           return;                
           }
      }

The result is that the formPage.php on submit remain on the same page, loading for ever. How to prevent this issue?

However I can still navigate the website clicking manually on links and make also other request..so the receiver it's running in background without problems.

Can you be more clear. Is initRpc.php the action when formPage is submitted or not? — JessGabriel, Feb 22 '19 at 17:38
Okey, so it is normal because the trigger itself is a part of PHP current process.To avoid this, you can use websocket to send the signal to the rabbiMQ workers — JessGabriel, Feb 22 '19 at 18:11
Thanks for help but can you be more specific or give me a simpler solution? — merovingio, Feb 22 '19 at 19:26
The problem is solved: i used ajax to call the script. This prevent the infinite loop loading but call remains in pending. — merovingio, Mar 10 '19 at 10:25
Have the same problem. Dont understand it. The Rabbit documentation code seems like a nonsense. I have endless script. Wau. — Čamo, Apr 28 '23 at 20:21
