    Example #1 Event::addSignal() example

    <?php
    /*
    Launch it in a terminal window:

    $ php examples/signal.php

    In another terminal window find out the pid and send SIGTERM, e.g.:

    $ ps aux | grep examp
    ruslan    3976  0.2  0.0 139896 11256 pts/1    S+   10:25   0:00 php examples/signal.php
    ruslan    3978  0.0  0.0   9572   864 pts/2    S+   10:26   0:00 grep --color=auto examp
    $ kill -TERM 3976

    At the first terminal window you should catch the following:

    Caught signal 15
    */
    class MyEventSignal {
        private     $base, $ev;

        public function     __construct($base) {
                $this->base = $base;
                $this->ev = Event::signal($base, SIGTERM, array($this, 'eventSighandler'));
                $this->ev->addSignal();
        }

        public function     eventSighandler($no, $c) {
            echo     "Caught signal $no\n";
                $this->base->exit();
        }
    }

    $base = new EventBase();
    $c    = new MyEventSignal($base);

    $base->loop();
    ?>
