$y2 = (isset($_GETї'endY']))?$_GETї'endY'] : 50;
$img = imagecreate(100,100);
$color = imagecolorallocate ($img, 200, 200, 200);
imagerectangle($img, 0,0,99,99, $color);
$color = imagecolorallocate ($img, 255, 0, 0);
imageline($img, 0, $y1, 99, $y2, $color);

Code: Select all
$y1 = (isset($_GETї'startY']))?$_GETї'startY'] : 50;
This would equate to:
Code: Select all
if (isset($_GETї'startY'])) {
$y1 = $_GETї'startY'];
} else {
$y1 = 50;
}
