Question

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）

并输出：

Firefox 3.6.13（Windows XP）

或者也许：

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

思考？这是否存在？

Answer 1

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
    );
} 

// now try it
$ua=getBrowser();
$yourbrowser= "Your browser: " . $ua['name'] . " " . $ua['version'] . " on " .$ua['platform'] . " reports: <br >" . $ua['userAgent'];
print_r($yourbrowser);
?>

Answer 2

您可以使用get_browser()，但请阅读底部的说明：您的责任是保持browscap文件的最新状态。

Answer 3

您可以使用get_browser()。 PHP文档是一个强大的工具！

Answer 4

似乎许多Web浏览器退出并发现甚至不同版本或不同网站浏览器代表相同的用户代理字符串也很困难。因此，很难创造出这样的东西。可以找到用户代理列表here

但我发现非常好small program here。它的运行速度非常快，并将用户代理字符串更改为：

Your Computer Info
==================
Operating System:    Windows

以上输出是由小程序脚本提供的，它还检测维护移动网站浏览器和机器人的主要列表，这是我现在看到的惊人。

是否有PHP库或脚本将UA转换为人性化的浏览器ID＆amp;版？
