我正在尝试找到一个php函数，允许我查看用户正在使用的Windows版本，并且在您告诉我不是每个人都使用Windows之前，我正在使用此功能来教育并为人们提供Internet Explorer的替代浏览器 - 仅限Windows的浏览器。
我希望能够检测到所有 9 个版本的窗口，这在 php 中可能吗？
你可以试试$_SERVER['HTTP_USER_AGENT'] .在这里你可以找到一个很好的例子。
您可以使用
$_SERVER['HTTP_USER_AGENT'];
或
$browser = get_browser(null, true);
print_r($browser);
检查 获取浏览器 php.net .
这里有一些很好的代码来做你想做的事情
<?php
$OSList = array
(
// Match user agent string with operating systems
'Windows 95' => '(Windows 95)|(Win95)|(Windows_95)',
'Windows 98' => '(Windows 98)|(Win98)',
'Windows 2000' => '(Windows NT 5.0)|(Windows 2000)',
'Windows XP' => '(Windows NT 5.1)|(Windows XP)',
'Windows Server 2003' => '(Windows NT 5.2)',
'Windows Vista' => '(Windows NT 6.0)',
'Windows 7' => '(Windows NT 6.1)',
'Windows 8' => '(Windows NT 6.2)',
'Windows 8.1' => '(Windows NT 6.3)',
'Windows NT 4.0' => '(Windows NT 4.0)|(WinNT4.0)|(WinNT)|(Windows NT)',
'Windows ME' => 'Windows ME'
);
// Loop through the array of user agents and matching operating systems
foreach($OSList as $CurrOS=>$Match)
{
// Find a match
if (eregi($Match, $_SERVER['HTTP_USER_AGENT']))
{
// We found the correct match
break;
