array Worker::$connections

The format is

array(id=>connection, id=>connection, ...)

This property stores all the client connection objects of the current process, where id is the id number of the connection, details can be found in the manual TcpConnection id property.

$connections is very useful when broadcasting or getting a connection object based on the connection id.

If the id of the connection is known as $id, it is very convenient to get the corresponding connection object through $worker->connections[$id] in order to operate the corresponding socket connection, for example, sending data through $worker->connections[$id]->send('...').

Note: If the connection is closed (triggering onClose), the corresponding connection will be removed from the $connections array.

Note: Developers should not make modifications to this property, as it may cause unpredictable situations.
