PHP exif_read_data返回错误和不完整的数据

Question

我正在尝试使用exif_read_data从我的图像中读取一些exif数据。但是，似乎返回的数据部分错误或不完整。

您可以查看this image，其中显然包含大量exif数据，如in this exif reader所示。

尝试阅读相机型号（exif键＆＃34;型号＆＃34;）然而返回我名字的一部分和相机制造商（exif键＆＃34; Make＆＃34;）甚至没有显示。< / p>

我使用print_r(exif_read_data($imageUrl, 'EXIF, IFD0'));记录了所有信息，结果如下：

如您所见，＆＃34;模型＆＃34;和＆＃34;制造＆＃34;是可用的，但它们包含错误的信息。 （对于像＆＃34;软件＆＃34;）这样的键也是如此。
