PHP ET::trigger方法代码示例

 /**
  * Triggers an event, returning an array of return values from event handlers.
  *
  * Two events will actually be triggered: one prefixed with the name of this class,
  * one not. For example, if an instance of ETPluggable calls $this->trigger("eventName"),
  * both "ETPluggable_eventName" and "eventName" events will be triggered.
  *
  * The event handlers are called with $this as the first argument, and optionally any extra
  * $parameters. The return values from each handler are collected and then returned in an array.
  *
  * @param string $event The name of the event.
  * @param array $parameters An array of extra parameters to pass to the event handlers.
