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(); ?>
The above example will output something similar to:
Caught signal 15
