what diagram?
here's a small example (of something

)

Code: Select all

&lt;?php
$y1 = (isset($_GET&#1111;'startY']))?$_GET&#1111;'startY'] : 50;
$y2 = (isset($_GET&#1111;'endY']))?$_GET&#1111;'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);

header('Content-type: image/png');
imagepng($img);
?&gt;

have a look at http://www.php.net/manual/en/ref.image.php

heavy -

Code: Select all

$y1 = (isset($_GET&#1111;'startY']))?$_GET&#1111;'startY'] : 50;

This would equate to:

Code: Select all

if (isset($_GET&#1111;'startY'])) {
   $y1 = $_GET&#1111;'startY'];
} else {
   $y1 = 50;
}
