thinkphp 控制器中 display()方法实现的原理
thinkphp 控制器中 display()方法实现的原理是什么
     display()方法中可以不填写参数 根据调用的方法名称来自动查找模板文件
     请问这是怎么实现的 他是怎么获取调用的方法名称的
      
     请大家共同探讨下  最好能写个能实现这样的功能的代码 或 关键方法和思路

你搜索一下,读读他的源码不就知道了

        define('MODULE_NAME',self::getModule(C('VAR_MODULE')));<br />
        define('ACTION_NAME',self::getAction(C('VAR_ACTION')));<br />

    static private function getModule($var)<br />
    {<br />
        $module = (!empty($_GET[$var])? $_GET[$var]:C('DEFAULT_MODULE'));<br />
        if(C('URL_CASE_INSENSITIVE')) {<br />
            // URL地址不区分大小写<br />
            define('P_MODULE_NAME',strtolower($module));<br />
            // 智能识别方式 index.php/user_type/index/ 识别到 UserTypeAction 模块<br />
            $module = ucfirst(parse_name(P_MODULE_NAME,1));<br />
        }<br />
        unset($_GET[$var]);<br />
        return $module;<br />
    }<br />
<br />
    /**<br />
