如何获得确切的浏览器名称和版本?


72

我已经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;

上面代码的输出:

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

但是我正在使用:

Google Chrome 11.0.696.68
on   
Ubuntu 10.04

因此,我可以Chrome/11.0.696.68在输出字符串中找到它,但是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

周围有很多很好的UserAgent解析器。您可以尝试在此处列出的解析器之一github.com/ThaDafinser/UserAgentParser

确保您可以通过php.ini访问browscap.ini文件,以确保所有建议的解决方案都能正常工作。请查看以下注释:php.net/manual/en/function.get-browser.php#101125

采用 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

您需要browscap.ini才能正常工作。browscap.ini未与PHP捆绑在一起...它依赖于用户更新来保持数据库为最新。这使它的使用很麻烦。

请记住,这get_browser使用的是browsercap.ini,这是一个胖文件,当前大于2MByte。如果在一个脚本中多次使用该功能,则使用此功能将导致处理大量内容,这可能会导致脚本损坏。

也许您可以使用此$ _SERVER ['HTTP_USER_AGENT']这在PHP中是一个不变的魔力

该JavaScript为您提供浏览器名称和版本,

var browser = '';
var browserVersion = 0;

if (/Opera[\/\s](\d+\.\d+)/.test(navigator.userAgent)) {
    browser = 'Opera';
} else if (/MSIE (\d+\.\d+);/.test(navigator.userAgent)) {
    browser = 'MSIE';
} else if (/Navigator[\/\s](\d+\.\d+)/.test(navigator.userAgent)) {
    browser = 'Netscape';
} else if (/Chrome[\/\s](\d+\.\d+)/.test(navigator.userAgent)) {
    browser = 'Chrome';
} else if (/Safari[\/\s](\d+\.\d+)/.test(navigator.userAgent)) {
    browser = 'Safari';
    /Version[\/\s](\d+\.\d+)/.test(navigator.userAgent);
    browserVersion = new Number(RegExp.$1);
} else if (/Firefox[\/\s](\d+\.\d+)/.test(navigator.userAgent)) {
    browser = 'Firefox';
}
if(browserVersion === 0){
    browserVersion = parseFloat(new Number(RegExp.$1));
}
alert(browser + "*" + browserVersion);

任何反对的理由?如果原因是,这不是PHP,您是否看到他在问题中提到PHP?如果他只想得到PHP答案,为什么问题是JavaScript和jQuery的标记?

jQuery和JavaScript中的+1答案也是可以接受的。这就是为什么我添加了这些标签。

您能否在2015年测试该脚本。使用IE不会显示任何内容。

在2019年,Edge和Opera将返回= Chrome

@webchun我认为这是因为Edge使用铬

在这里得到了很棒的功能。

    $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';

这在Opera上不起作用-我建议进行修改以解决该问题
ConorReidd '16

我们也可以在此功能中获得平台版本吗?
卡维亚·史瑞

谢谢,按预期方式工作,并已在Chrome,Edge和Firefox中进行了测试。
无效

为什么使用带有此简单代码的大量代码; $ _ SERVER ['HTTP_USER_AGENT']您可以获得浏览器的名称
simon 19'October

尊敬的@Parag Tyagi,它返回错误“未定义变量:ub”,需要设置ub变量的默认值。谢谢。

该类无法检测IE11。function checkBrowserInternetExplorer()添加开始时:if( stripos($this->_agent,'Trident/7.0; rv:11.0') !== false ) { $this->setBrowser(self::BROWSER_IE); $this->setVersion('11.0'); return true; } else if( ...

该类的改写是可用的。它本身支持IE 11.

使用get_browser() 功能

它可以为您提供如下输出:

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
    .... 

看到这些评论,为什么你可能不希望使用get_browser()- stackoverflow.com/questions/8754080/...

  • (Safari)和(Opera)和(Chrome)之间有冲突!

  • 上面的代码无法正常工作

这是我的代码,它运行良好,没有任何冲突:

function ExactBrowserName()
{

$ExactBrowserNameUA=$_SERVER['HTTP_USER_AGENT'];

if (strpos(strtolower($ExactBrowserNameUA), "safari/") and strpos(strtolower($ExactBrowserNameUA), "opr/")) {
    // OPERA
    $ExactBrowserNameBR="Opera";
} elseIf (strpos(strtolower($ExactBrowserNameUA), "safari/") and strpos(strtolower($ExactBrowserNameUA), "chrome/")) {
    // CHROME
    $ExactBrowserNameBR="Chrome";
} elseIf (strpos(strtolower($ExactBrowserNameUA), "msie")) {
    // INTERNET EXPLORER
    $ExactBrowserNameBR="Internet Explorer";
} elseIf (strpos(strtolower($ExactBrowserNameUA), "firefox/")) {
    // FIREFOX
    $ExactBrowserNameBR="Firefox";
} elseIf (strpos(strtolower($ExactBrowserNameUA), "safari/") and strpos(strtolower($ExactBrowserNameUA), "opr/")==false and strpos(strtolower($ExactBrowserNameUA), "chrome/")==false) {
    // SAFARI
    $ExactBrowserNameBR="Safari";
} else {
    // OUT OF DATA
    $ExactBrowserNameBR="OUT OF DATA";
};

return $ExactBrowserNameBR;
}

我修改了此功能,以遵循PSR-2标准并检测IE11。这里是。很抱歉依赖外部网站,但是评论的限制迫使我这样做,而且我认为这不是一个不同的解决方案。经过Opera,Chrome,Firefox和IE的测试。我没有安装Safari,对不起。

我用PHP语言创建了一个函数,以获取浏览器名称,浏览器版本,操作系统(Windows / Linux等)以及设备类型(台式机/移动设备/平板电脑)。

谢谢兄弟,它很简单,很好。是的,解决了我的浏览器检测问题

由于某些代码给Edge和Opera带来了错误的结果,我建议尝试以下代码:

$popularBrowsers = ["Opera","OPR/", "Edg", "Chrome", "Safari", "Firefox", "MSIE", "Trident"];

$userAgent = $_SERVER['HTTP_USER_AGENT'];
$userBrowser = 'Other less popular browsers';
foreach ($popularBrowsers as $browser) {
    if (strpos($userAgent, $browser) !== false) {
        $userBrowser = $browser;
        break;
    }
}

switch ($userBrowser) {
    case 'OPR/':
        $userBrowser = 'Opera';
        break;
    case 'MSIE':
        $userBrowser = 'Internet Explorer';
        break;

    case 'Trident':
        $userBrowser = 'Internet Explorer';
        break;

    case 'Edg':
        $userBrowser = 'Microsoft Edge';
        break;
}

echo "Your browser: " . $userBrowser;

使用51Degrees.com设备检测解决方案来检测浏览器名称,供应商和版本。

首先,按照4步指南将设备检测器整合到您的项目中。当我说“合并”时,我的意思是下载包含PHP代码和数据库文件的存档,将它们解压缩并包括2个文件。这就是所有要做的。

完成后,您可以使用以下属性获取浏览器信息:
$ _51d ['BrowserName'] -为您提供浏览器的名称(Safari,Molto,Motorola,MStarBrowser等)。
$ _51d ['BrowserVendor'] -给您创建浏览器的公司。
$ _51d ['BrowserVersion'] -浏览器的版本号
