Generating a QR

Hi i need to generate a QR, (QR ISO/IEC 18004:2000)

Using some data

re= 
rr=
tt=
id=

Here is an example of a chain.

$data = "?re=AAA010101AAA&rr=CAJR820905IP1&tt=116.00&id= 556bef95-8322-4897-ae65-3b5e9de593f8";

I have found this link:

http://phpqrcode.sourceforge.net/examples/index.php?example=001

I have not idea at all, of how to build a QR using my data and that library, can anyone point at my stupidity pls..

thanks

EDIT Here is the real answer that i get thanks to the advice wich point me in the rigth direction. (thats why i mark it as correct answer). Anyway, someone may need this.

To genereate a QR (CBB in other countries) you can use the library http://phpqrcode.sourceforge.net/

Follow this. Create a file to generate the QR, in my case (/common/qrcode.php)

Inside this file you must insert the code to generate QR, depending on what you need. This example03 its pretty good for this.

include('phpqrcode/qrlib.php'); 

 $param = $_GET['id']; // remember to sanitize that - it is user input! 

    // we need to be sure ours script does not output anything!!! 
    // otherwise it will break up PNG binary! 

    ob_start("callback"); 

    // here DB request or some processing 
    $codeText = 'DEMO - '.$param; 

    // end of processing here 
    $debugLog = ob_get_contents(); 
    ob_end_clean(); 

    // outputs image directly into browser, as PNG stream 
    QRcode::png($codeText);

Then in your view or page where you want to display the QR, you can do this, 

$ourParamId = 1234; 

     echo '<img src="/common/qrcode.php?id='.$ourParamId.'" />';

Hopes this helps someone.

Well, the link that you have mentioned in the question is the answer:

<?php 

    include('../lib/full/qrlib.php'); 

    // outputs image directly into browser, as PNG stream 
    QRcode::png('PHP QR Code :)');

So you can have a page which accepts the data and displays the QR code as an image and you can have a script that reads the image and save it to DB or filesystem.

Hope this helps!

Check out : example 3.

A QR Code simply represents a text string. 

 // here DB request or some processing 
$codeText = 'DEMO - '.$param;  
$codeText = 'YOUR TEXT GOES HERE';
