當使用流動裝置傳取桌面版的網頁時，會自動移至流動裝置版的分頁
判斷瀏覽器是否流動裝置便需要先觀察 User Agent……
當使用網頁瀏覽器時，會提供稱為 User Agent 的訊息，訊息通常會包括：
使用者使用的作業系統名稱、作業系統版本、瀏覽器名稱、瀏覽器版本、排版引擎名稱、排版引擎版本
當能力分折 User Agent 的資料，便可以獲得使用者的作業系統名稱從判斷是否流動裝置，便可以轉移至合適的網頁版本
甚至可以獲得使用者的瀏覽器的預設語言，當使用存取網頁時讓網頁設換至相對語言，讓網頁更加人性化

只需要利用 regex 尋找對應該的名稱就完成操作，例如作業系統
使用 Linux 其 user agent 會使用 x11 或 Linux 的代號，可以利用
1 | /(x11|linux)/i |
在 PHP 的 preg_match 操作上，capturing group 會將資料傳回給第三個參數，相反 non-capturing group 則不會傳回
善用 non-capturing group 可以避免收集不必要的資料，例如在下的 regex 經常出現如
1 | /(?:(?:(?:linux)|(?:x11))(?:\ ((?:[0-9]+)(?:[\.\-\_][0-9]+)*))?)/i |
而需分析版本的 ((?:[0-9]+)(?:[\.\-\_][0-9]+)*))? 則使用 capturing group
另外還需要注意編程次序
一般程式碼由於會以上至下方式閱讀資料，若果某作業系統、瀏覽器，是另一個作業系統、瀏覽器的子集、衍生版
子集的程式碼必須比其父項編排得前，例如作業系統
Linux Mint 是 Ubuntu 的子集，Ubuntu 是 Debian 的子集，Debian 的 Linux 的子集
程式碼便必須以 Linux Mint, Ubuntu, Debian, Linux 或類似的次序編排
否則父項比子集次序編排為前時，子集將不會被閱讀
