Question

How does PHP handle client connection while doing sleeps?

Or put another way … what happens if the client closes the connection to the server while a page is being processed?

Does it just kill the process, or does it continue to process the page until the end?

Since I’m not sure of the answers to the above how would I implement the following pseudocode in PHP.

Record user entered  while (user is still connected) {     fetch changes in state since last awake     send changes to user      sleep(5); }  Record user exit 

Any thoughts would be appreciated.

Thanks.

Who knew?

Connection Handling Documentation – http://php.net/manual/en/features.connection-handling.php

From that page register_shutdown_function solves the problem.

Wonderful.
