Thinkphp5Summary of Behavior Usage Methods

Create a behavior directory under the application or module, and build a behavior class file Test.PHP inside the directory (here taking the home module as an example)

namespace app/home/behavior;//Note the different namespaces of the application or module 
class Test 
{ 
public function run(&$params)
{   
echo $params;  
}

Method One

1In the entry file, add: define('APP_HOOK', true);

2Define the behavior in tags.PHP under the .home module

return [  
'app_init' => [  
'app//home//behavior//Test', //Note the namespace of the behavior (as follows) 
], 
'zzzzz' => [//Custom tag position   
'app//home//behavior//Test', 
], 
//................. ];

3Listen to the behavior within the controller method where needed

/think/Hook::listen('app_init', $params);//The parameter is a variable (as follows) /think/Hook::listen('zzzzz', $params);//Custom

Method Two

1.The common file (common.PHP) of the .home module or bind behavior to tag positions within the controller method

/think/Hook::add('app_init', 'app//home//behavior//Test'); /think/Hook::add('zzzz', 'app//home//behavior//Test');//Custom

2Listen to the behavior within the controller method where needed

/think/Hook::listen('app_init', $params); /think/Hook::listen('zzzzz', $params);//Custom

Method Three

Execute the behavior directly at the required place within the controller method

/think/Hook::exec('app}}//home//behavior//Test', 'run', $params);

Method Four

Use closure functions directly within the controller method

$a='Closure function'; /think/Hook::add('zzzz', function($a){ var_dump($a);}); /think/Hook::listen('zzzz', $a);

Method Five

Behavior class bound to multiple tags

1.Test.PHP is defined as follows:

namespace app/home/behavior;
class Test {  
public function app_init(&$params){  
echo 'app_init';  } 
 public function app_end(&$params){   
echo 'app_end';  
}

2.The common file (common.PHP) of the .home module or bind behavior to tag positions within the controller method

/think/Hook::add('app_init', 'app//home//behavior//Test');
/think/Hook::add('app_end', 'app//home//behavior//Test');

3Listen to the behavior within the controller method where needed

/think/Hook::listen('app_init', $params); /think/Hook::listen('app_end', $params);
