int $center_x, int $center_y,
int $width, int $height, int $color )
where,
$image = The image identifier
$center_x = The x-coordinate - the center point
$center_y = The y-coordinate - the center point
$width = The width of the ellipse
$height = The height of the ellipse
$color = The fill color as returned by imagecolorallocate
