With Server-Sent Events (SSE) does PHP not reach the max_execution_time?

Question

All the examples of SSE that I have looked at use an infinite while loop plus sleep cmd on the server side to fetch data and return it to the client side - does the PHP max_execution_time not come into effect here? Or am I missing something obvious?

Thanks

Answer 1

max_execution_time will stop that php script, but SSE reconnects automatically
