理想情况下，这样的脚本会将用户代理（浏览器）字符串作为输入，例如：

Mozilla/5.0 (Windows; U; Windows NT 6.1; en-US; rv:1.9.2.13) Gecko/20101203 Firefox/3.6.13 (.NET CLR 3.5.30729)

和输出：

火狐 3.6.13 (Windows XP)

或者可能：

array('os' => 'Windows XP', 'browser' => 'Firefox', version => '3.6.13')

想法？这存在吗？

function getBrowser()

    $bname = 'Unknown';
    $platform = 'Unknown';

    //First get the platform?

print_r($yourbrowser);

您可以使用get_browser()，但请阅读底部的注释：您有责任使 browscap 文件保持最新。

您可以使用get_browser()。PHP 文档是一个强大的工具！

似乎很难，因为许多 Web 浏览器退出并发现即使是不同的版本或不同的网站浏览器也代表相同的用户代理字符串。因此，很难创建这样的东西。用户代理列表可以在这里找到

但是我在这里找到了非常好的小程序。它确实运行得非常快，并将用户代理字符串更改为：

Your Computer Info
==================
Operating System:    Windows
NT 5.1 (Windows XP)
Current Browser / UA: Mozilla/ Firefox 19.0
ProductSub: 20100101
Layout Engine: Gecko
Engine Version: 19.0

HTML Support
HTML 5 Basic: Good
HTML 5 Forms: Good
XHTML: Yes

System Language    
Primary Language id: en-us
Primary Language: English (United States)
Current Screen Resolution: 1366 x 768 pixels
JavaScript: JavaScript is enabled.
Cookies: Cookies are enabled
PHP Browser Detection: Run Time: 0.00032091 Seconds

上面的输出是由小程序的脚本提供的，它还检测维护移动网站浏览器和机器人的主要列表，这是我迄今为止看到的惊人的。
