Codeigniter Datamapper ORM php 7 静态问题

Question

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

Message: Accessing static property DataMapper::$config as non static
Filename: libraries/datamapper.php Line Number: 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。要修复它，请尝试添加新的 protected 静态方法

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

    return $CI->config;
}

然后删除或注释 6474 和 6481 行(在 _dmz_assign_libraries 中，其中值被分配给 $this->config )，

最后替换所有调用 $this->config与 self::get_config_object()
现在应该可以正常运行了。
