如何在别人之前运行方法？

Question

I need to run one private method before some others public methods, so i used __call method which seems to override default method calling so it looks like this

function __call($method, $arguments)
{
    // echo($method);

    if (in_array($method, array('changeStatus', 'lockStatus'))) 
        $this->_checkInputData($arguments);

    call_user_func($method, $arguments);
}

But i'm suddenly noticed that __call method works only on non-defined methods, so is there any way to call custom method before specified?

Answer 1

This question is a bit odd. To call private method before public you can call it in your public method example

class Example
{
   private function methodA()
   {
     echo 'I am a method A';
   }

   public function methodB()
   {
     $this->methodA();
     echo 'I am a method B';
   }
}

in that way when you call methodB on object it will call firstly methodA and then body of method B.

Edit

you wanted to specify what method should be called.

class Example
{
   private function methodA()
   {
     echo 'I am a method A';
   }

   private function methodB()
   {
     echo 'I am a method B';
   }

   public function callMethods($method)
   {
      if($method =='a') $this->methodA();
      else if($method =='b') $this->methodA();
      //rest of function  
   }
}

In this way you can specify in

$obj = new Example();
$obj->callMethods('a'); // will call firstly MethodA
$obj->callMethods('b'); // will call firstly MethodB
