PHP判斷瀏覽器類型和瀏覽器語言(附各國語言簡寫代碼)

用php語言來判斷瀏覽器類型其實很簡單。

因為瀏覽器在和伺服器串連時候都會先發送一些包含自己資訊的內容（瀏覽器類型、語言啦）。

這裡我們主要分析的是_SERVER["HTTP_USER_AGENT"](瀏覽器類型)和_SERVER["HTTP_ACCEPT_LANGUAGE"](瀏覽器語言)。

 

我們所要做的就是把這些內容讀出來，然後用strpos或者preg_match函數來對比就可以了。

判斷瀏覽器類型:

<?php echo $_SERVER["HTTP_USER_AGENT"]; ?>  

判斷瀏覽器語言:

<?php echo $_SERVER["HTTP_ACCEPT_LANGUAGE"]; ?>

判斷瀏覽器類型的具體程式如下:

<?phpif(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 8.0"))echo "Internet Explorer 8.0";else if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 7.0"))echo "Internet Explorer 7.0";else if(strpos($_SERVER["HTTP_USER_AGENT"],"MSIE 6.0"))echo "Internet Explorer 6.0";else if(strpos($_SERVER["HTTP_USER_AGENT"],"Firefox/3"))echo "Firefox 3";else if(strpos($_SERVER["HTTP_USER_AGENT"],"Firefox/2"))echo "Firefox 2";else if(strpos($_SERVER["HTTP_USER_AGENT"],"Chrome"))echo "Google Chrome";else if(strpos($_SERVER["HTTP_USER_AGENT"],"Safari"))echo "Safari";else if(strpos($_SERVER["HTTP_USER_AGENT"],"Opera"))echo "Opera";else echo $_SERVER["HTTP_USER_AGENT"];?>

判斷瀏覽器語言的具體程式如下:

<?php$lang = substr($_SERVER['HTTP_ACCEPT_LANGUAGE'], 0, 4); //只取前4位，這樣只判斷最優先的語言。如果取前5位，可能出現en,zh的情況，影響判斷。if (preg_match("/zh-c/i", $lang))echo "簡體中文";else if (preg_match("/zh/i", $lang))echo "繁體中文";else if (preg_match("/en/i", $lang))echo "English";else if (preg_match("/fr/i", $lang))echo "French";else if (preg_match("/de/i", $lang))echo "German";else if (preg_match("/jp/i", $lang))echo "Japanese";else if (preg_match("/ko/i", $lang))echo "Korean";else if (preg_match("/es/i", $lang))echo "Spanish";else if (preg_match("/sv/i", $lang))echo "Swedish";else echo $_SERVER["HTTP_ACCEPT_LANGUAGE"];?>

判斷瀏覽器類型主要是靠分析_SERVER["HTTP_USER_AGENT"]的內容，而分析瀏覽器語言則是分析_SERVER["HTTP_ACCEPT_LANGUAGE"]。

或者：

function getPreferredLanguage() {$langs = array();if (isset($_SERVER['HTTP_ACCEPT_LANGUAGE'])) {// break up string into pieces (languages and q factors)preg_match_all('/([a-z]{1,8}(-[a-z]{1,8})?)s*(;s*qs*=s*(1|0.[0-9]+))?/i',$_SERVER['HTTP_ACCEPT_LANGUAGE'], $lang_parse);if (count($lang_parse[1])) {// create a list like "en" => 0.8$langs = array_combine($lang_parse[1], $lang_parse[4]);// set default to 1 for any without q factorforeach ($langs as $lang => $val) {if ($val === '') $langs[$lang] = 1;}// sort list based on valuearsort($langs, SORT_NUMERIC);}}//extract most important (first)foreach ($langs as $lang => $val) { break; }//if complex language simplify itif (stristr($lang,"-")) {$tmp = explode("-",$lang); $lang = $tmp[0]; }return $lang;}
