Use of thinkphp behavior

The simple point of behavior is that the program performs an operation that is automatically invoked at a certain step, such as the following

First step, add behavior tab bit

$param $ids ; Hook:: Listen (' Event_reject ',$param);

Parameter $param Optional

Second step, behavior binding

Binding in the Tags.php file under project directory App_path

return [    ' event_stop_publish ' =>[' app\\qikan\\behavior\\stoppublish '];

The third step, the behavior definition at the binding behavior location

namespace App\index\behavior; class Test {    publicfunction app_init (&$param)    {        //  $params Pass for reference     }        publicfunction app_end (&$ param)    {    }    }
