	      o $width
		- The arc width.

	      o $height
		- The arc height.

	      o $start
		- The arc start angle, in degrees.

	      o $end

EXAMPLES

       Example #1

	      Drawing a circle with imagearc(3)

	      <?php

	      // create a 200*200 image
	      $img = imagecreatetruecolor(200, 200);

	      // allocate some colors
	      $white = imagecolorallocate($img, 255, 255, 255);
	      $red   = imagecolorallocate($img, 255,   0,   0);
	      $green = imagecolorallocate($img,   0, 255,   0);
	      $blue  = imagecolorallocate($img,   0,   0, 255);

	      // draw the head
	      imagearc($img, 100, 100, 200, 200,  0, 360, $white);
	      // mouth
	      imagearc($img, 100, 100, 150, 150, 25, 155, $red);
	      // left and then the right eye
	      imagearc($img,  60,  75,	50,  50,  0, 360, $green);
	      imagearc($img, 140,  75,	50,  50,  0, 360, $blue);

	      o $x2
		- Bottom right x coordinate.

	      o $y2
		- Bottom right y coordinate.

	      o $color
