获取浏览器类型

$_SERVER['HTTP_USER_AGENT']包含了用户代理字符串，该字符串包含了浏览器、操作系统等信息。通过分析这个字符串，可以大致判断用户使用的浏览器类型。

<?phpfunction getBrowserType() {$userAgent = $_SERVER['HTTP_USER_AGENT'];$browser = "Unknown Browser";if (preg_match('/MSIE/i', $userAgent) || preg_match('/Trident/i', $userAgent)) {$browser = "Internet Explorer";} elseif (preg_match('/Edge/i', $userAgent)) {$browser = "Microsoft Edge";} elseif (preg_match('/Firefox/i', $userAgent)) {$browser = "Mozilla Firefox";} elseif (preg_match('/Chrome/i', $userAgent) && preg_match('/Safari/i', $userAgent) == false) {$browser = "Google Chrome";} elseif (preg_match('/Safari/i', $userAgent)) {$browser = "Apple Safari";} elseif (preg_match('/Opera/i', $userAgent) || preg_match('/OPR/i', $userAgent)) {$browser = "Opera";}return $browser;
}echo "Browser Type: " . getBrowserType();?>

获取浏览器语言

$_SERVER['HTTP_ACCEPT_LANGUAGE']包含了用户首选的语言列表，通常以逗号分隔，并带有质量值（可选）。可以通过解析这个字符串来获取用户的首选语言。

<?phpfunction getBrowserLanguage() {$acceptLanguage = $_SERVER['HTTP_ACCEPT_LANGUAGE'];$languages = explode(',', $acceptLanguage);$primaryLanguage = 'Unknown Language';if (isset($languages[0])) {// 提取语言代码（通常是前两个字符）$primaryLanguageCode = substr($languages[0], 0, 2);// 映射语言代码到可读语言名称（可选）$languageMap = ['en' => 'English','zh' => 'Chinese','fr' => 'French','de' => 'German','es' => 'Spanish',// 可以根据需要添加更多语言映射];$primaryLanguage = isset($languageMap[$primaryLanguageCode]) ? $languageMap[$primaryLanguageCode] : $primaryLanguageCode;}return $primaryLanguage;
}echo "Browser Language: " . getBrowserLanguage();?>
