get_browser()方法

可获取浏览器具有的功能。注意：为了能让该函数有效运作，需要在 php.ini 中配置的browscap，指向 browscap.ini 文件。browscap.ini 并未内置在PHP中，此处下载： » php_browscap.ini。
browscap.ini 内的信息会不定期更新，建议每隔一两年更新一次该文件。

配置：

1，下载php_browscap.ini文件。文件有三几种，不同文件包含的信息不一样，下面会详细介绍。找个适合自己的下载，放到服务器某个位置，记住路径，在php.ini中使用。假设为：/wwwroot/browser_cap/php_browscap.ini
2，打开php.ini，结尾添加代码，如下：

[browscap]
; https://www.php.net/manual/zh/misc.configuration.php#ini.browscap
browscap = "/wwwroot/browser_cap/php_browscap.ini"
