Are there any recommended PHP libraries or frameworks for generating thumbnails?

Generating thumbnails in PHP can be done using libraries or frameworks that provide functions for image manipulation. One recommended library for generating thumbnails in PHP is Intervention Image, which simplifies the process of resizing and manipulating images. By using this library, you can easily generate thumbnails of images in various formats.

// Include the Intervention Image library
require 'vendor/autoload.php';

use Intervention\Image\ImageManagerStatic as Image;

// Load an image from a file
$img = Image::make('example.jpg');

// Resize the image to create a thumbnail
$img->resize(100, null, function ($constraint) {
    $constraint->aspectRatio();
})->save('thumbnail.jpg');
