PHP扩展命名空间\类未知错误

这是我的父类代码：\core\controller\controlmaster

<?php
namespace core\controller;

class controlmaster{
private $model_base = null;

//public function __construct(){
    //always start session for any loaded controller
    //session_start();        
//}

public function _loadModels($models){
    $file = dirname(dirname(__DIR__)).DIRECTORY_SEPARATOR.$this->model_base.$models.".php";
    $file_alloc = str_replace("\\","/",$file);
    if(file_exists($file_alloc)){
        require($file_alloc);
        $models_name = $this->model_base.$models;
        return new $models_name();  
    }
}

public static function _setModelBase($model_location){
    $this->model_base = $model_location;    
}
}
?>

这是应用程序：\applications\controller\index的我的控制器页面

<?php
namespace applications\controllers;

use core\configuration\configloader as config;

class index extends \core\controller\controlmaster{
public $config;

public function __construct(){
    $this->config = new config;
    $this->config->_parsePHP("j3mp_setting.php");
    parent::_setModelBase($this->config->settings['app_model_base']);   // Error doesn't appear when i comment this function
    echo "This is main page and this is config for model app base : {$this->config->settings['base_url']}"; 
}
}
?>

这是core\configuration\configloader：

<?php
namespace core\configuration;
class configloader{
//Contains setting informations
public $inisettings;
public $settings;

public function _parseINI($file,$section){
    $section = empty($section) ? false : true;
    $file = __DIR__.DIRECTORY_SEPARATOR.$file;
    if(file_exists($file)){
        $parse = parse_ini_file($file,$section);
        $this->inisettings = $parse;
    }else{
        throw new core\errorhandler\exception("File {$file} is not found in our system. Please contact administrator for details.","configloader");
    }
}

public function _parsePHP($file){
    $file = __DIR__.DIRECTORY_SEPARATOR.$file;
    if(file_exists($file)){
        $settings = array();
        include($file);
        $this->settings = $settings;    
    }else{
        throw new core\errorhandler\exception("File {$file} is not found in our system. Please contact administrator for details.","configloader");
    }
}
}
?>

当我注释parent:：_setModelBase时。。。代码，错误消失，浏览器成功打印这是主页，这是模型应用程序库的配置：。我认为错误来自\core\controller\controlmaster，但我不知道如何修复它？我总是试图编辑文件\core\controller\controlmaster，但没有发生。。。如果发生错误，则消息“这是主页面…”。。。没有出来。。。你能告诉我错误是从哪里来的吗？谢谢…

core\configuration\configloader的内容是什么？configloader用于加载配置文件，不应包括$file$此->设置=$settings；be$settings=include$file？调用\u setModelBase之前，$this->config->settings['app\u model\u base']的值是多少？@prodigitalson:使用静态或自存储时总是出错。。。
