### `imagepalettecopy` example

    <?php
    // Create two palette images
    $palette1 = imagecreate(100, 100);
    $palette2 = imagecreate(100, 100);

    // Allocate the background to be
    // green in the first palette image
    $green = imagecolorallocate($palette1, 0, 255, 0);

    // Copy the palette from image 1 to image 2
    imagepalettecopy($palette2, $palette1);

    // Since the palette is now copied we can use the
    // green color allocated to image 1 without using
    // imagecolorallocate() twice
    imagefilledrectangle($palette2, 0, 0, 99, 99, $green);

    // Output image to the browser
    header('Content-type: image/png');

    imagepng($palette2);
    imagedestroy($palette1);
    imagedestroy($palette2);
    ?>
