PHP 手冊中有檢查瀏覽器版本的函數 get_browser()

但這個函數沒經過設定是無法使用的

echo $_SERVER['HTTP_USER_AGENT'];
echo "<br/>"; 
// 第一個參數可以指定user agent，第二個參數設為true回傳陣列，否則回傳物件
$browser = get_browser(null, true);
print_r($browser);

執行

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:53.0) Gecko/20100101 Firefox/53.0
Warning: get_browser(): browscap ini directive not set in xxx.php

設定

一、下載 browscap.ini

http://browscap.org/

可選下載PHP browscap.ini的版本有輕量版、完整版或一般版本 ，此檔必須手動更新，以免新版本的瀏覽器無法辨識。

# cd /etc/php.d/
# wget http://browscap.org/stream?q=PHP_BrowsCapINI -O browscap.ini

二、修改 php.ini ，我使用絕對路徑，以免出現錯誤

尋找[browscap]這個tab，加入一行

重新啟動 APACHE

三、重新執行

我下載完整版本後執行的結果

此錯誤發生原因為 php.ini的設定檔指定的 browscap.ini找不到，請將他設為絕對路徑或註解掉";"可解決。
