這個是最近寫的一個php獲取圖片Exif類，功能比較全面，也把所有的Exif都翻譯了，執行效率也還可以。
唉，這次懶地寫英文版了，以后有時間把英文版也做下。同樣，不設置隱藏，也不需金錢。
因為這里不能貼鏈接，我博客里有個測試網頁，大家如果有興趣，可以去看看tonylevid.com
分兩大模式：一個是已經轉換數據的（如width:500px）用於顯示；一個是未轉換數據的如（width:500）用於用戶自己自定義計算。
內置3種獲取模式，用戶可以自定義數組來獲取。
注意：需在php.ini中開啟mbstring和exif模塊
功能如下：
@可以獲取已經轉換后的值，也可以獲取未轉換的值用於自己自定義計算
@內置3種獲取模式，分別為簡要信息、常用信息和全部信息
@用戶可以自定義獲取信息
具體可以查看類中的注釋
