What are the differences between using ImageCreateTrueColor and ImageCreate in image resizing functions?

When resizing images in PHP using the GD library, it is important to use `ImageCreateTrueColor` instead of `ImageCreate` to ensure that the resized image maintains its quality and does not lose any information. `ImageCreateTrueColor` creates a new true color image, while `ImageCreate` creates a palette-based image which may result in loss of quality during resizing.

// Using ImageCreateTrueColor for resizing images
function resizeImage($sourceImage, $newWidth, $newHeight) {
    $source = imagecreatefromjpeg($sourceImage);
    $destination = imagecreatetruecolor($newWidth, $newHeight);
    imagecopyresampled($destination, $source, 0, 0, 0, 0, $newWidth, $newHeight, imagesx($source), imagesy($source));
    return $destination;
}
