如何获得准确的浏览器名称和版本？

Question

我尝试了一些解决方案，但无法获得确切的名称和版本：

我正在尝试以下代码：

 $browserAgent = $_SERVER['HTTP_USER_AGENT'];
echo $browserAgent;

上述代码的输出：

 Mozilla/5.0 (X11; Linux i686) AppleWebKit/534.24 (KHTML, like Gecko) Chrome/11.0.696.68 Safari/534.24

但我正在使用：

 Google Chrome 11.0.696.68
on
Ubuntu 10.04

所以我可以在输出字符串中找到 Chrome/11.0.696.68 但它也显示了一些其他浏览器名称，这些名称令人困惑，无法从字符串中提取确切的浏览器 名称/版本。

Answer 1

使用 get_browser()

从手册：

 echo $_SERVER['HTTP_USER_AGENT'] . "\n\n";

$browser = get_browser(null, true);
print_r($browser);

将返回：

 Array
(
    [browser_name_regex] => ^mozilla/5\.0 (windows; .; windows nt 5\.1; .*rv:.*) gecko/.* firefox/0\.9.*$
    [browser_name_pattern] => Mozilla/5.0 (Windows; ?; Windows NT 5.1; *rv:*) Gecko/* Firefox/0.9*/
    [parent] => Firefox 0.9
    [platform] => WinXP
    [browser] => Firefox
    [version] => 0.9
    [majorver] => 0
    [minorver] => 9
    [cssversion] => 2
    [frames] => 1
    [iframes] => 1
    [tables] => 1
    [cookies] => 1
    [backgroundsounds] =>
    [vbscript] =>
    [javascript] => 1
    [javaapplets] => 1
    [activexcontrols] =>

    [aol] =>
    [beta] => 1
    [win16] =>
    [crawler] =>
    [stripper] =>
    [wap] =>
    [netclr] =>
)

在此处 获取此功能并进行了更新。它适用于 Edge 浏览器。

 <?php
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';
        $ub = "Firefox";
    }
    elseif(preg_match('/OPR/i',$u_agent))
    {
        $bname = 'Opera';
        $ub = "Opera";
    }
    elseif(preg_match('/Chrome/i',$u_agent) && !preg_match('/Edg/i',$u_agent))
    {
        $bname = 'Google Chrome';
        $ub = "Chrome";
    }
    elseif(preg_match('/Safari/i',$u_agent) && !preg_match('/Edg/i',$u_agent))
    {
        $bname = 'Apple Safari';
        $ub = "Safari";
    }
    elseif(preg_match('/Netscape/i',$u_agent))
    {
        $bname = 'Netscape';
        $ub = "Netscape";
    }
    elseif(preg_match('/Edg/i',$u_agent))
    {
        $bname = 'Edge';
        $ub = "Edg";
    }
    elseif(preg_match('/Trident/i',$u_agent))
    {
        $bname = 'Internet Explorer';
        $ub = "MSIE";
    }

    // 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 [
        'userAgent' => $u_agent,
        'name'      => $bname,
        'version'   => $version,
        'platform'  => $platform,
        'pattern'    => $pattern
    ];
}

// invoke function
$arBrowser =  getBrowser();
echo '<pre>';
print_r($arBrowser);
echo '</pre>';
?>
