[PHP]Token Opcje

[moto0095]

Witam znalazłem ostatnio i przerobiłem pewien token.
Tylko nie wiem jak dodać do niego jakieś plamki, kreski itp. w tle.
oto kod:

[PHP] pobierz, plaintext 
<?php
session_start(); //rozpoczecie sesji
header ('Content-type: image/png');  //wyslanie naglowkow do przegladarki
header ('Expires: '.gmdate ('r', 0));
header ('Last-Modified: '.gmdate ('r'));
header ('Cache-Control: no-store, no-cache, must-revalidate');
header ('Pragma: no-cache');
 
$chars = array(1,2,3,4,5,6,7,8,9,'e','r','t','u','i','p','a','g','h','j','z','c','b','n','m'); //Lista znakow
 
for($i = 0; $i < 6; $i++)              //Losowanie znakow
{
    $text .= $chars[array_rand($chars)];
}
 
$_SESSION['token'] = $text;
//Tworzenie obrazka
$image = imagecreatetruecolor(100, 32);
$background = imagecolorallocate($image, 0, 0, 0);
 
imagefill($image, 0, 0, $background);
 
$textcolor = imagecolorallocate($image, 255, 255, 255);
imagestring($image, 10, 25, 8, $text, $textcolor);
 
imagepng($image);
 
imagedestroy ($Image);
?>

Wiem że to ta funkcja tylko nie wiem jak ją podpiąć.

Okey poradziłem sobie jakoś.
Oto kod może się komuś przyda (IMG:style_emoticons/default/smile.gif)

Aby nie zaczynać nowego tematu to zapytam się tutaj.
Jak zrobić odświeżanie tego tokena po kliknięciu na przycisk np: "Inny", ale bez przeładowania strony (wiem że można to zrobić w ajaxie tylko ja nie znam go w ogóle ) (IMG:style_emoticons/default/questionmark.gif) (IMG:style_emoticons/default/questionmark.gif) (IMG:style_emoticons/default/questionmark.gif)
