Why doesn't variables work in image strings?

[Ajm113]

I want to create a image string that retrieves the params of the url to put on the image in php like so:

image.php?user= Ajm113

Then it should print the user on the image string, but for some reason it doesn't work. Is it more then that?

you need to $_GET['user'] to use the string.

Try this:

<?php
$text = $_GET['user'];

$im = imagecreate(100, 20);
$bg = imagecolorallocate($im, 200, 200, 200);
$fg = imagecolorallocate($im, 0, 0, 255);

imagestring($im, 3, 5, 3, $text, $fg);

header("Content-type: image/png");
imagepng($im);
?>

call the script with something like image.php?user= myusername
