利用php获取图片完整Exif信息类 获取图片详细完整信息类
这个是最近写的一个php获取图片Exif类，功能比较全面，也把所有的Exif都翻译了，执行效率也还可以。
唉，这次懒地写英文版了，以后有时间把英文版也做下。同样，不设置隐藏，也不需金钱。
因为这里不能贴链接，我博客里有个测试网页，大家如果有兴趣，可以去看看tonylevid.com
分两大模式：一个是已经转换数据的（如width:500px）用于显示；一个是未转换数据的如（width:500）用于用户自己自定义计算。
内置3种获取模式，用户可以自定义数组来获取。
注意：需在php.ini中开启mbstring和exif模块
功能如下：
@可以获取已经转换后的值，也可以获取未转换的值用于自己自定义计算
@内置3种获取模式，分别为简要信息、常用信息和全部信息
@用户可以自定义获取信息
具体可以查看类中的注释
