How can the connection timeout for a ReactPHP socket client be summarized?

edit

The connection timeout for a ReactPHP socket client can be summarized as the amount of time that the client will wait for a connection to be established with the server before timing out and throwing an exception. This timeout can be set using the setTimeout() method on the client object, and is measured in seconds. It is important to set a reasonable timeout value to prevent the client from waiting indefinitely for a connection that may never be established.
