What are the differences between ImageCopyResized and ImageCopyResampled functions in PHP, and how do they impact image quality?

The main difference between ImageCopyResized and ImageCopyResampled functions in PHP is how they handle image resizing. ImageCopyResized simply resizes the image without considering image quality, which can result in a loss of quality. On the other hand, ImageCopyResampled uses a more advanced algorithm to resize the image while maintaining better quality. Using ImageCopyResampled is recommended when resizing images to ensure better quality.

// Using ImageCopyResampled to resize an image while maintaining quality
$source = imagecreatefromjpeg('source.jpg');
$destination = imagecreatetruecolor(200, 200);
imagecopyresampled($destination, $source, 0, 0, 0, 0, 200, 200, imagesx($source), imagesy($source));
imagejpeg($destination, 'resized_image.jpg');
imagedestroy($source);
imagedestroy($destination);
