How can PHP be used to combine individual letter images into a single cohesive image for display on a webpage?

To combine individual letter images into a single cohesive image for display on a webpage, you can use PHP's image processing functions to create a new image canvas, then overlay the individual letter images onto this canvas to form the final image. This can be achieved by loading each letter image, determining their positions on the canvas, and then merging them together. Finally, the resulting image can be displayed on the webpage using PHP. 

// Create a new image canvas
$finalImage = imagecreatetruecolor($width, $height);

// Load individual letter images
$letterA = imagecreatefrompng('letterA.png');
$letterB = imagecreatefrompng('letterB.png');
$letterC = imagecreatefrompng('letterC.png');

// Determine positions of individual letter images on the canvas
$positions = [
    ['image' => $letterA, 'x' => 0, 'y' => 0],
    ['image' => $letterB, 'x' => 50, 'y' => 0],
    ['image' => $letterC, 'x' => 100, 'y' => 0],
];

// Merge individual letter images onto the final image canvas
foreach ($positions as $position) {
    imagecopy($finalImage, $position['image'], $position['x'], $position['y'], 0, 0, imagesx($position['image']), imagesy($position['image']));
}

// Output the final image
header('Content-Type: image/png');
imagepng($finalImage);
imagedestroy($finalImage);
