query string not displayed

[Anon]

i've got a test code with imagecreate
when i use a query string like http://localhost/test.php?string=Hello

my imagestring code is:
imagestring($im, 2, 4, 1, $string, $text_color);

but when i try it, it doesn't display a thing, just the background.
when i use:
imagestring($im, 2, 4, 1, "Hello", $text_color);

it does work

anyone got an idea??

Use $_GET['string'] instead of just $string.
