Exif data is metadata embedded within digital photos, containing details like the shooting time, device model, resolution, and more. By reading Exif data, you can obtain valuable information behind a photo, including the manufacturer information.
Before starting, make sure your server has PHP installed and the Exif extension enabled. You can verify the PHP version with the following command:
php -v
Then check if the Exif extension is enabled:
php -m | grep exif
If the Exif extension is not enabled, please install and activate it according to your system environment.
Use PHP's built-in exif_read_data function to read all the Exif information of a photo. Example code:
$exif_data = exif_read_data('path/to/photo.jpg');You can use var_dump to view the full Exif data structure:
var_dump($exif_data);
Typically, the manufacturer information is stored in the Make field, and sometimes in the Manufacturer field. Example extraction code:
$make = $exif_data['Make'];<br>$manufacturer = $exif_data['Manufacturer'];
The variables $make and $manufacturer now hold the manufacturer information of the photo.
$exif_data = exif_read_data('path/to/photo.jpg');<br>$make = $exif_data['Make'];<br>$manufacturer = $exif_data['Manufacturer'];<br>echo 'Make: ' . $make;<br>echo 'Manufacturer: ' . $manufacturer;This code will output the manufacturer information of the photo directly, making it easy to use and display in applications.
Reading photo metadata using PHP combined with the Exif extension is a simple and effective method. Extracting manufacturer information is useful for photo categorization, device analysis, and more. With just a few lines of code, you can quickly get device information from photos and easily integrate it into various PHP projects.
