PHP in a Nutshell

Name

connection_status()

Synopsis

    int connection_status ( void )

The connection_status() function takes no parameters and returns 0 if the connection is live and execution is still taking place; 1 if the connection is aborted; 2 if the connection has been aborted; and 3 if the connection has been aborted and subsequently timed out.

The last situation is only possible if ignore_user_abort(true) has been used, and the script subsequently timed out. The values 0, 1, 2, and 3 evaluate to the constants CONNECTION_NORMAL, CONNECTION_ABORTED, CONNECTION_TIMEOUT, and CONNECTION_ABORTED | CONNECTION_TIMEOUT (a bitwise OR of the previous two).

This script can tell the difference between shutdown occurring because the script finished or because script timeout was reached:

    function say_goodbye() {
            if (connection_status() =  = CONNECTION_TIMEOUT) {
                    print "Script timeout!\n";
            } else {
                    print "Goodbye!\n";
            }
    }

    register_shutdown_function("say_goodbye");
    set_time_limit(1);
    print "Sleeping...\n";
    sleep(2);
    print "Done!\n";
