Synchronous vs. Asynchronous operations
By default this client is configured to work in a synchronous mode, which means that for every command (except CONNECT) the client will wait for the receipt . You can set the client to work in the asynchronous mode, by setting the sync property of the StompConnection object to false.
Asynchronous client
$conn = new Stomp("tcp://localhost:61613"); $conn->sync = false;
You can also perform single operations in desired mode, no matter of the global client settings, by passing additional parameter to the appropriate method
Asynchronous method
$this->conn->send("/queue/test", "test", null, true);
Some things you have to consider when deciding whether to use synchrnous os asynchronous mode
- When you use asynchronous mode broker errors will be ignored
- Asynchronous method allows you to send messages faster, since will not wait for broker's response
