How can the PHP script be modified to ensure that the final image output is transparent?

To ensure that the final image output is transparent, you can set the image format to PNG and use the `imagealphablending()` and `imagesavealpha()` functions to enable alpha channel support for transparency in PHP. 

// Create a new true color image with transparency
$image = imagecreatetruecolor($width, $height);

// Enable alpha blending
imagealphablending($image, false);

// Save alpha channel information
imagesavealpha($image, true);

// Fill the image with a transparent background
$transparent = imagecolorallocatealpha($image, 0, 0, 0, 127);
imagefill($image, 0, 0, $transparent);

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