TP5中文件的写入路径有的会被自动重定向到首页

 public function export()
    {
        $model=model(‘FanweUser‘);
        $list=$model->where("mobile!=‘‘")->field("mobile")->limit(50000)->select();
 
        foreach($list as $k=>$v) 
        {
            $handle = fopen("3.txt", "a");
            $aa=$v[‘mobile‘]."\r\n";
            if ($handle) {
                fwrite($handle, $aa);
            }
            fclose($handle);
        }
        
    }
