Example

Let us see another example wherein we have different coordinates and angle for arc:

<?php
$img = imagecreatetruecolor(250, 250);
$one = imagecolorallocate($img, 100, 90, 255);
$two = imagecolorallocate($img, 100, 255, 190);  
imagearc($img, 130, 100, 200, 200, 0, 360, $one);
imagearc($img, 140, 50, 140, 150, 95, 155, $two);
header("Content-type: image/png");
