What is the best way to position or insert a smaller image into a larger image using PHP?

When positioning or inserting a smaller image into a larger image using PHP, you can use the GD library functions to manipulate images. You can create a new image with the dimensions of the larger image, copy the larger image onto it, and then copy the smaller image onto the desired position on the new image. This can be achieved by using functions like imagecreatefromjpeg(), imagecopyresampled(), and imagejpeg(). 

// Load the larger image
$largeImage = imagecreatefromjpeg('large.jpg');
$largeWidth = imagesx($largeImage);
$largeHeight = imagesy($largeImage);

// Load the smaller image
$smallImage = imagecreatefromjpeg('small.jpg');
$smallWidth = imagesx($smallImage);
$smallHeight = imagesy($smallImage);

// Position the smaller image at coordinates (x, y) on the larger image
$x = 100; // Example x coordinate
$y = 50; // Example y coordinate

// Copy the smaller image onto the larger image
imagecopy($largeImage, $smallImage, $x, $y, 0, 0, $smallWidth, $smallHeight);

// Save the final image
imagejpeg($largeImage, 'final.jpg');

// Free up memory
imagedestroy($largeImage);
imagedestroy($smallImage);
