How can the gd library in PHP be used to save a section of images as a single image?

To save a section of images as a single image using the gd library in PHP, you can create a new image, copy the sections of images you want to include into the new image, and then save the new image. This can be achieved by using functions like imagecreatefromjpeg(), imagecopy(), and imagejpeg() provided by the gd library. 

// Create a new image with the desired width and height
$newImage = imagecreatetruecolor($newWidth, $newHeight);

// Copy sections of images into the new image
imagecopy($newImage, $image1, $x1, $y1, $srcX1, $srcY1, $width1, $height1);
imagecopy($newImage, $image2, $x2, $y2, $srcX2, $srcY2, $width2, $height2);

// Save the new image as a JPEG file
imagejpeg($newImage, 'output.jpg');

// Free up memory by destroying the images
imagedestroy($newImage);
imagedestroy($image1);
imagedestroy($image2);
