Question

我已经编写了用于检测bworser名称的脚本，下面是os和broser vesion的代码。

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

此脚本仅返回更粗略的名称，plathform（os名称），但不返回brwoser的返回版本。我不知道这是什么问题。

上面的脚本在我的Windows服务器上给出了浏览器名称和版本的输出，但没有在亚马逊服务器上获取。

如果有任何其他方式获取浏览器名称，请提示版本。

您应该使用get_browser功能。

Here是PHP手册

您需要按照PHP手册说明中的说明设置browscap.ini文件。以下是sample ini文件

如何获取浏览器名称，版本？
