如果Windows下载$ win_file如果Mac下载$ mac_file

Question

嗨，我有一个小问题！

我有一个应用程序的“下载”按钮，但它适用于Windows和Mac两个平台。 我想自动化该过程，当客户端点击下载按钮时，我需要浏览器自动识别OS平台。

并取决于此应该是这样的：如果Windows下载$win_file如果Mac下载$mac_file

如何在PHP中做到这一点？

谢谢！

Answer 1

您可以使用useragent字符串，并通过以下代码获取它：

$userAgent = $_SERVER['HTTP_USER_AGENT'];

它会给你这样的东西：

Mozilla/5.0 (Macintosh; Intel Mac OS X 10_7_4) AppleWebKit/534.57.2 (KHTML, like Gecko) Version/5.1.7 Safari/534.57.2

您将必须像下面这样检查此字符串：

if(strpos($userAgent, "Win") !== FALSE) {
    // Execute windows code
} elseif(strpos($userAgent, "Mac") !== FALSE) {
    // Execute mac code
}

Google告诉我看一下该网站： http : //www.danielkassner.com/2010/06/11/get-user-operating-system-with-php

<?php
/*

function getOS($userAgent) {
  // Create list of operating systems with operating system name as array key 
    $oses = array (
        'iPhone' => '(iPhone)',
        'Windows 3.11' => 'Win16',
        'Windows 95' => '(Windows 95)|(Win95)|(Windows_95)', // Use regular expressions as value to identify operating system
        'Windows 98' => '(Windows 98)|(Win98)',
        'Windows 2000' => '(Windows NT 5.0)|(Windows 2000)',
        'Windows XP' => '(Windows NT 5.1)|(Windows XP)',
        'Windows 2003' => '(Windows NT 5.2)',
        'Windows Vista' => '(Windows NT 6.0)|(Windows Vista)',
        'Windows 7' => '(Windows NT 6.1)|(Windows 7)',
        'Windows NT 4.0' => '(Windows NT 4.0)|(WinNT4.0)|(WinNT)|(Windows NT)',
        'Windows ME' => 'Windows ME',
        'Open BSD'=>'OpenBSD',
        'Sun OS'=>'SunOS',
        'Linux'=>'(Linux)|(X11)',
        'Safari' => '(Safari)',
        'Macintosh'=>'(Mac_PowerPC)|(Macintosh)',
        'QNX'=>'QNX',
        'BeOS'=>'BeOS',
        'OS/2'=>'OS/2',
        'Search Bot'=>'(nuhk)|(Googlebot)|(Yammybot)|(Openbot)|(Slurp/cat)|(msnbot)|(ia_archiver)'
    );

    foreach($oses as $os=>$pattern){ // Loop through $oses array
    // Use regular expressions to check operating system type
        if(eregi($pattern, $userAgent)) { // Check if a value in $oses array matches current user agent.
            return $os; // Operating system was matched so return $oses key
        }
    }
    return 'Unknown'; // Cannot find operating system so return Unknown
}
?>

<?php
echo getOS($_SERVER['HTTP_USER_AGENT']);
?>

应该可以使用了，但是还没有尝试过。
