Example #1 Event::addSignal() example
<?php/*Launch it in a terminal window:$ php examples/signal.phpIn another terminal window find out the pid and send SIGTERM, e.g.:$ ps aux | grep exampruslan 3976 0.2 0.0 139896 11256 pts/1 S+ 10:25 0:00 php examples/signal.phpruslan 3978 0.0 0.0 9572 864 pts/2 S+ 10:26 0:00 grep --color=auto examp$ kill -TERM 3976At 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
