以下是我已经照顾过的事情：
从http://tempdownloads.browserscap.com/下载了php_browscap.ini的更新副本（使用'仅限PHP使用'版本的课程）
尝试了php_browscap.ini，lite_php_browscap.ini和full_php_browscap.ini 3.将php.ini文件编辑为：[browscap]
;http://php.net/browscap
browscap = "C:\xampp\php\extras\full_php_browscap.ini"
通过检查php_info（）
并删除了;来自'; browscap = .....'
重申了xampp服务器。
但仍然得到奇怪的值
