用PHP实现操作系统的远程检测

user-agent头可能会显示一些操作系统信息,但我不指望。

对于您的用例,我将从客户端使用javascript进行ajax调用,以通知您的服务器客户端的操作系统。

下面是一个例子。

Javascript(客户端、浏览器检测+ajax调用): detection script from here )

window.addEvent('domready', function() { 
  if (BrowserDetect) { 
    var q_data = 'ajax=true&browser=' + BrowserDetect.browser + '&version=' + BrowserDetect.version + '&os=' + BrowserDetect.OS; 
    var query = 'record_browser.php' 
    var req = new Request.JSON({url: query, onComplete: setSelectWithJSON, data: q_data}).post(); 
  } 
}); 

if ($_SERVER['REQUEST_METHOD'] == 'POST') { 
    $session = session_id(); 
    $user_id = isset($user_id) ? $user_id ? 0; 
    $browser = isset($_POST['browser']) ? $_POST['browser'] ? ''; 
    $version = isset($_POST['version']) ? $_POST['version'] ? ''; 
    $os = isset($_POST['os']) ? $_POST['os'] ? ''; 

    // now do here whatever you like with this information
} 

您可以查看用户代理标头( $_SERVER['HTTP_USER_AGENT']

Mozilla/5.0(iPhone;U;CPU) iPhone操作系统 3_0 如Mac OS X;en us) AppleWebKit/420.1(KHTML,比如Gecko)

Windows XP可能看起来像:

Mozilla/5.0(Windows;U; Windows NT ;en-US;rv:1.9.2.10)壁虎/20100914火狐/3.6.10

here . 你也可以使用 get_browser() (你需要 browscap 尽管如此)

请注意,此标头很容易被伪造,因此不应用于任何关键任务。

不可靠? $_SERVER['HTTP_USER_AGENT'] 通常包含操作系统信息。

    function getBrowser()
    {
        $u_agent = $_SERVER['HTTP_USER_AGENT'];
        $bname = 'Unknown';
        $platform = 'Unknown';
        $version= "";

        //First get the platform?
        if (preg_match('/linux/i', $u_agent)) {
            $platform = 'linux';
        }
        elseif (preg_match('/macintosh|mac os x/i', $u_agent)) {
            $platform = 'mac';
        }
        elseif (preg_match('/windows|win32/i', $u_agent)) {
            $platform = 'windows';
        }

        // Next get the name of the useragent yes seperately and for good reason
        if(preg_match('/MSIE/i',$u_agent) && !preg_match('/Opera/i',$u_agent))
        {
            $bname = 'Internet Explorer';
            $ub = "MSIE";
        }
        elseif(preg_match('/Firefox/i',$u_agent))
        {
            $bname = 'Mozilla Firefox';
            $ub = "Firefox";
        }
        elseif(preg_match('/Chrome/i',$u_agent))
        {
            $bname = 'Google Chrome';
            $ub = "Chrome";
        }
        elseif(preg_match('/Safari/i',$u_agent))
        {
            $bname = 'Apple Safari';
            $ub = "Safari";
        }
        elseif(preg_match('/Opera/i',$u_agent))
        {
            $bname = 'Opera';
            $ub = "Opera";
        }
        elseif(preg_match('/Netscape/i',$u_agent))
        {
            $bname = 'Netscape';
            $ub = "Netscape";
        }

        // finally get the correct version number
        $known = array('Version', $ub, 'other');
        $pattern = '#(?<browser>' . join('|', $known) .
        ')[/ ]+(?<version>[0-9.|a-zA-Z.]*)#';
        if (!preg_match_all($pattern, $u_agent, $matches)) {
            // we have no matching number just continue
        }

        // see how many we have
        $i = count($matches['browser']);
        if ($i != 1) {
            //we will have two since we are not using 'other' argument yet
            //see if version is before or after the name
            if (strripos($u_agent,"Version") < strripos($u_agent,$ub)){
                $version= $matches['version'][0];
            }
            else {
                $version= $matches['version'][1];
            }
        }
        else {
            $version= $matches['version'][0];
        }

        // check if we have a number
        if ($version==null || $version=="") {$version="?";}

        return array(
            'userAgent' => $u_agent,
            'name'      => $bname,
            'version'   => $version,
            'platform'  => $platform,
            'pattern'    => $pattern
        );
    }

var_dump(getBrowser());

get_browser 函数将为您解析$\u SERVER['HTTP\u USER\u AGENT']。你需要浏览CAP.ini不过。

与其自己实现,我宁愿尝试使用现有的软件,比如 Browser.php 为您解析用户代理字符串。你需要考虑的小事情太多了,最好使用一个专门的库,而不是自己去学习所有这些平台/浏览器不一致的地方。
