如何获得准确的浏览器名称和版本？

小开

最佳答案

使用强 > get_browser()强

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

使用 get_browser() 功能。

它可以给你这样的输出:

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

这个 JavaScript 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);

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，按照四步指南将设备检测器合并到项目中。当我说合并，我的意思是下载与 PHP 代码和数据库文件归档，解压缩他们，包括2个文件。这就是合并的全部内容。

完成后，您可以使用以下属性获取浏览器信息:
$_ 51d [‘ BrowserName’] -给出浏览器名称(Safari、 Molto、 Motorola、 MStarBrowser 等)。
$_ 51d [‘ BrowserVendor’] -提供创建浏览器的公司。
$_ 51d [‘ BrowserVersion’] -浏览器的版本号

由于一些代码给了 Edge 和 Opera 错误的结果，我建议尝试下面的代码:

$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;
