COdeigniter Datamapper ORM php 7静态问题

Question

当我将我的服务器升级到php7 codeigniter,特别是datamapper ORM给我这个错误...

消息:访问静态属性DataMapper :: $ config为非静态
文件名:libraries/datamapper.php行号:6474

有问题的功能是......

protected function _dmz_assign_libraries()
{
    static $CI;
    if ($CI || $CI =& get_instance())
    {
        // make sure these exists to not trip __get()
        $this->load = NULL;
        $this->config = NULL;
        $this->lang = NULL;
        // access to the loader
        $this->load =& $CI->load;
        // to the config
        $this->config =& $CI->config;
        // and the language class
        $this->lang =& $CI->lang;
    }
}

我也有同样的问题。要修复此问题，请尝试添加新的受保护的静态方法

protected static function get_config_object() {
    $CI =& get_instance();

    return $CI->config;
}

然后删除或注释行6474和6481（在中_dmz_assign_libraries，将值分配给$this->config），

最后将所有通话替换$this->config为self::get_config_object()

现在应该可以正确运行了。
