[PHP] Get value from external

[Snell]

I have search for a script for writing text into an image and so far I've got this

<?php
header ("Content-type: image/gif");
$string = "your text";
// try changing this as well
$font = 4;
$width = imagefontwidth($font) * strlen($string) ;
$height = imagefontheight($font) ;
$im = imagecreatefromgif("link-to-image");
$x = 120;
$y = 4;
$backgroundColor = imagecolorallocate ($im, 255, 255, 255);
$textColor = imagecolorallocate ($im, 0, 0,0);
imagestring ($im, $font, $x, $y,  $string, $textColor);
imagegif($im);
?>

However I don't know who to change the string $string externally.

That is if I execute it like this

text-image.php?t=image in test

I should the text "image in test" in the image.

Anyone can help me out?

sorry if I've not used the correct terms to explain my problem
