Thinkphp5 behavior hook return result (data) example

Reading guide ：

In some scenes , We use behavior hooks Hook Do something , The result should be returned after execution （ data ）, The returned value may be a string 、 Numbers or arrays . Don't know how to use behavior hook , First look at my previous article ：

Thinkphp5.0 Action Hook Hook Usage of _ Mu CHENFENG's blog -CSDN Blog _thinkphp hook

step ：

1 、 stay application/common.php Add the following methods to the public function file ：

// Monitor a hook 
function hook($hook,$params=array()){
	// hinder true Parameter means to get only one valid return value , That is, only get the first element of the array 
    return \Think\Hook::listen($hook,$params,null,true);
}

2、 stay application/tags.php Define behavior hooks

//  Application behavior extension definition file 
return [
    //  Application initialization 
    'app_init'     => [],
    //  App start 
    'app_begin'    => [],
    //  Module initialization 
    'module_init'  => [],
    //  The operation begins 
    'action_begin' => [],
    //  View content filtering 
    'view_filter'  => [],
    //  Log write 
    'log_write'    => [],
    //  End of application 
    'app_end'      => [],
    // +----------------------------------------------------------------------
    // |  Custom behavior hook 
    // +----------------------------------------------------------------------
	'sendData'    => ['app\behavior\Order'],
];

3、 Add a behavior file application/behavior/Order.php, The sample code is as follows ：

<?php
namespace app\behavior;
use think\Db;

/**
 *   If there is only one behavior in this behavior class , Just define a behavior entry method `run` that will do 
 */
class Order 
{     
    //  When the behavior class is bound to the hook ,run The behavior method will be executed when the hook is triggered 
    public function run($params){
        //  Behavioral logic 
    }
    // A custom behavior method 
	public function sendData($params){
		try{
			// All business logic is omitted here 
            $data=array(
				"code" => 1,
				"msg"  => ' Data sent successfully '
			);
		} catch (\Exception $e) {
			$data=array(
				"code" => 0,
				"msg"  => ' Sending data exception ,Error：'.$e->getMessage()
			);
		}
		return $data;
	}
}

Look at the code to see ,Order.php Inside sendData() Method returns an array

4、 Call behavior method

// Use behavior hooks to send data 
$params=array(
	"account"=> "qq1234",
	"money"  => 10,
);
// It returns an array 
$arr= hook('sendData',$params);
