Question

在PHP 7.2上，内置函数exif_read_data向PHP 7.1返回不同的信息

这是我使用7.2时得到的：

php -r 'var_export(exif_read_data("x.jpg", "ANY_TAG"));'

array (
  'FileName' => 'x.jpg',
  'FileDateTime' => 1543144462,
  'FileSize' => 3564506,
  'FileType' => 2,
  'MimeType' => 'image/jpeg',
  'SectionsFound' => 'ANY_TAG, IFD0, EXIF',
  'COMPUTED' => 
  array (
    'html' => 'width="3968" height="2976"',
    'Height' => 2976,
    'Width' => 3968,
    'IsColor' => 1,
    'ByteOrderMotorola' => 1,
  ),
  'ImageWidth' => 3968,
  'ImageLength' => 2976,
  'BitsPerSample' => 
  array (
    0 => 8,
    1 => 8,
    2 => 8,
  ),
  'ImageDescription' => 'ptr',
  'Make' => 'HUAWEI',
  'Model' => 'STF-L09',
  'Orientation' => 0,
  'XResolution' => '72/1',
  'YResolution' => '72/1',
  'ResolutionUnit' => 2,
  'Software' => 'STF-L09C432B120',
  'DateTime' => '2018:11:24 15:11:58',
  'YCbCrPositioning' => 1,
)

但是当我在7.1上运行完全相同的代码时，我得到了更多的EXIF数据：

array (
  'FileName' => 'x.jpg',
  'FileDateTime' => 1543144462,
  'FileSize' => 3564506,
  'FileType' => 2,
  'MimeType' => 'image/jpeg',
  'SectionsFound' => 'ANY_TAG, IFD0, THUMBNAIL, EXIF, GPS, INTEROP',
  'COMPUTED' => 
  array (
    'html' => 'width="3968" height="2976"',
    'Height' => 2976,
    'Width' => 3968,
    'IsColor' => 1,
    'ByteOrderMotorola' => 1,
    'ApertureFNumber' => 'f/2.2',
    'Thumbnail.FileType' => 2,
    'Thumbnail.MimeType' => 'image/jpeg',
    'Thumbnail.Height' => 384,
    'Thumbnail.Width' => 512,
  ),
  'ImageWidth' => 3968,
  'ImageLength' => 2976,
  'BitsPerSample' => 
  array (
    0 => 8,
    1 => 8,
    2 => 8,
  ),
  'ImageDescription' => 'ptr',
  'Make' => 'HUAWEI',

  array (

    2 => '49994201/1000000',
  ),
  'GPSLongitudeRef' => 'W',
  'GPSLongitude' => 
  array (

  'GPSDateStamp' => '2018:11:24',
  'InterOperabilityIndex' => 'R98',
  'InterOperabilityVersion' => '0100',
)

使用7.2时，是否可以进行任何模块，扩展或更改以获得完整的EXIF数据？我在共享的Linux主机上，因此我只能做些限制。

Answer 1

这似乎是PHP中的错误-https://bugs.php.net/bug.php?id=72682和https://abi-laboratory.pro/index.php?view=changelog&l=php&v=7.2.3

唯一的答案是降级-或升级-没有错误的版本。

PHP 7.2上的exif_read_data不会返回所有元数据
