What are the best practices for handling image editing tasks, such as rounding corners, in PHP?

When handling image editing tasks such as rounding corners in PHP, one of the best practices is to use the GD library, which provides functions for image manipulation. To round the corners of an image, you can create a new image with rounded corners by overlaying a transparent rounded corner image on top of the original image. This can be achieved by creating a mask image with rounded corners and using the `imagecopymerge()` function to merge the original image with the mask image. 

// Load the original image
$originalImage = imagecreatefromjpeg('original.jpg');

// Create a mask image with rounded corners
$maskImage = imagecreatetruecolor(imagesx($originalImage), imagesy($originalImage));
$maskColor = imagecolorallocate($maskImage, 255, 255, 255);
imagefill($maskImage, 0, 0, $maskColor);
$radius = 50; // Adjust the radius as needed
imagefilledellipse($maskImage, $radius, $radius, $radius * 2, $radius * 2, $maskColor);
imagefilledellipse($maskImage, imagesx($maskImage) - $radius, $radius, $radius * 2, $radius * 2, $maskColor);
imagefilledellipse($maskImage, $radius, imagesy($maskImage) - $radius, $radius * 2, $radius * 2, $maskColor);
imagefilledellipse($maskImage, imagesx($maskImage) - $radius, imagesy($maskImage) - $radius, $radius * 2, $radius * 2, $maskColor);
imagefilltoborder($maskImage, 0, 0, $maskColor, $maskColor);

// Apply the mask to the original image
imagecopymerge($originalImage, $maskImage, 0, 0, 0, 0, imagesx($originalImage), imagesy($originalImage), 100);

// Output the modified image
header('Content-Type: image/jpeg');
imagejpeg($originalImage);

// Clean up
imagedestroy($originalImage);
imagedestroy($maskImage);
