Use this snippet of code to retrieve the kind of browser:
使用此代码片段检索浏览器类型：
if (isset($_SERVER['HTTP_USER_AGENT'])) {
$agent = $_SERVER['HTTP_USER_AGENT'];
}
Then, compare against the user agent string.
然后，与用户代理字符串进行比较。
For example, to detect "Firefox" you could do:
例如，要检测“Firefox”，您可以执行以下操作：
if (strlen(strstr($agent, 'Firefox')) > 0) {
$browser = 'firefox';
}

php's inbuilt function get_browser is your answer. or try using $_SERVER['HTTP_USER_AGENT'] or simply use this script http://chrisschuld.com/projects/browser-php-detecting-a-users-browser-from-php/

You can use the User-Agentheader in the request. Either you do a regex check on it to find Firefox specific patterns or you can use a library like WURFL that has a better chance of identifying the browser.
您可以User-Agent在请求中使用标头。您可以对其进行正则表达式检查以查找 Firefox 特定模式，或者您可以使用像 WURFL 这样的库来更好地识别浏览器。
See this answerfor an example on how to do it.

look in $_SERVER['HTTP_USER_AGENT']
在看 $_SERVER['HTTP_USER_AGENT']
e.g.: Mozilla/5.0 (Windows NT 5.1; rv:13.0a1) Gecko/20120206 Firefox/13.0a1
例如： Mozilla/5.0 (Windows NT 5.1; rv:13.0a1) Gecko/20120206 Firefox/13.0a1
