范例

Example #1 Event::addSignal() example

  <?php
 
 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 ();
 ?>

以上例程的输出类似于：

Caught signal 15
