如何獲取呼叫類的名稱（以PHP爲單位）

Question

define('anActionType', 1); 
$actionTypes = array(anActionType => 'anActionType'); 
class core { 
    public $callbacks = array(); 
    public $plugins = array(); 
    public function __construct() { 
     $this->plugins[] = new admin(); 
     $this->plugins[] = new client(); 
    } 
} 
abstract class plugin { 
    public function registerCallback($callbackMethod, $onAction) { 
     if (!isset($this->callbacks[$onAction])) 
      $this->callbacks[$onAction] = array(); 

     global $actionTypes; 
     echo "Calling $callbackMethod in $callbacksClass because we got {$actionTypes[$onAction]}" . PHP_EOL; 

     // How do I get $callbacksClass? 

     $this->callbacks[$onAction][] = $callbackMethod; 
    } 
} 
class admin extends plugin { 
    public function __construct() { 
     $this->registerCallback('onTiny', anActionType); 
    } 
    public function onTiny() { echo 'tinyAdmin'; } 
} 
class client extends plugin { 
    public function __construct() { 
     $this->registerCallback('onTiny', anActionType); 
    } 
    public function onTiny() { echo 'tinyClient'; } 
} 
$o = new core(); 

$callbacksClass應該是管理員或客戶端。或者我是否完全忽略了這一點，應該以另一種方式進行探討？應該指出，我將只接受一個答案，它不要求我將類名作爲參數發送到registerCallback方法。

Answer 1

使用get_class()：

$this->callbacks[$onAction][] = $callbackMethod; 
$className = get_class($this); 

// Call callback method 
$className->$callbackMethod(); 

Answer 2

你真的應該這樣做：

$this->registerCallback(array($this, 'onTiny'), anActionType); 

也就是說PHP如何與句柄對象的方法。

Answer 3

如果有人來到這裏尋找如何從另一個類，像我一樣得到了調用類的名字，看看這個https://gist.github.com/1122679

編輯：粘貼代碼

function get_calling_class() { 

    //get the trace 
    $trace = debug_backtrace(); 

    // Get the class that is asking for who awoke it 
    $class = $trace[1]['class']; 

    // +1 to i cos we have to account for calling this function 
    for ($i=1; $i<count($trace); $i++) { 
     if (isset($trace[$i])) // is it set? 
      if ($class != $trace[$i]['class']) // is it a different class 
       return $trace[$i]['class']; 
    } 
} 

EG

class A { 
    function t() { 
     echo get_calling_class(); 
    } 
} 

class B { 
    function x() { 
     $a = new A; 
     $a->t(); 
    } 
} 

$b = new B; 
$b->x(); // prints B
