I need to get the information inside the image with PHP, information like: Trademarks (or tags), Title, Comments, Authors and Copyright.

Does anyone know how to get this information using PHP?

    Do you want to say that they are in the image properties? or that it is written in the image?

Use the function exif_read_data

The function exif_read_data() reads the EXIF headers of a JPEG or TIFF image file. Returns an associative matrix where the indexes are the header names and the values are the values associated with these headers. If no data can be returned, then the result is FALSE.

To activate it in your php.ini remove the ; of the line:

  • If you are PHP 7.2 (windows, mac osx, linux):

    ;extension=exif

  • If Windows and version is earlier than PHP 7.2:

    ;extension=php_exif.dll

  • If Linux/Mac OSX and the version predates PHP 7.2:

    ;extension=exif.so

After removing the ;, just staying:

extension=exif

or

extension=php_exif.dll

or

extension=exif.so

Restart server, Apache, Nginx, etc

Note that in Windows you need to enable mbstring as well, so in PHP 7.2:

extension=mbstring

In previous versions of PHP:

extension=php_mbstring.dll

Example of usage code:

$exif = exif_read_data('tests/test1.jpg', 'IFD0');

$exif = exif_read_data('tests/test2.jpg', 0, true);

foreach ($exif as $key => $section) {
    foreach ($section as $name => $val) {
        echo "$key.$name: $val<br />\n";
    }
}

Note that PHP 7.2 added support for the following EXIF formats:

  • Samsung
  • DJI
  • Panasonic
  • Sony
  • Pentax
  • Minolta
  • Sigma/Foveon
  • AGFA
  • Kyocera
  • Ricoh
  • Epson
