Question: How does tick() run every one second. #130

Closed AndeYashwanth closed 4 years ago

In websockets.php how does the function tick() execute every second? Is it accidental that the tick() method happens to be executing approx once every second or it is intentional?

The call to socket_select() has the timeout intentionally set to 1 second. The call is on line 89, with the call to the tick() method shortly before that.

(Note for future versions: Let users configure this.)

This means that socket_select() will block and wait for a new message of any type for 1 second. If a message comes in sooner, that message will be processed, anything that you put into your tick() method will run, and socket_select() will be called again. If any messages came in while the rest of the script was working, that message will be picked up as soon as socket_select() is called; otherwise it will wait for up to a second again.
