如何获取调用类的名称（在PHP中） [英] How to get the name of the calling class (in PHP)

问题描述

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 应为管理员或客户端。或者我在这里完全错过了点，应该去另一种方式？应该注意，我只接受一个答案，不需要我把类名作为参数发送到registerCallback方法。

$callbacksClass should be admin or client. Or am I missing the point here completely and should go about this another way? It should be noted that I will only accept an answer that does not require me to send the classname as an argument to the registerCallback method.

推荐答案

使用 get_class（） ：

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

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