Listening
Listening is specific state in which you wait for emitted packages from ThingsDB. You can read more about it in docs. PHP has max_execution_time and it is not allowed to set higher value than this. With max_execution_time=0 you can of course wait indefinitely.
join
, emit
, leave
also emit package towards the one who did it. Therefore, don't be surprised when first package received with calling listening
will be ON_JOIN|ON_LEAVE|ON_EMIT
event type.
Example
:lock: SSL
To make connection with enabled SSL you can use third parameter of constructor which is context. This context is provided to stream_context_create when creating connection. verify_peer
is the bare minimum to enable SSL communication.
:stopwatch: Timeout
Class constructor contains $timeout
argument. This timeout is for established socket connection. To set up
timeout for establishing socket connection itself you have to set ini directive default_socket_timeout
.
_Setting up ini directive isn't part of connection class because function ini_set
can be disabled on production
environments for security reasons._
