(1) Download the PHP QR Code Library on the official website , download the source files and extract them to the Phpqrcode directory.

(2) Create a script file create_png.php Add the user form on the page with the following code:

<form method= "POST" >

$temp = './images/'; define the path of the two-dimensional code picture

$filename =time (). "              Test.png "; Generate picture name

$filename = $temp. $filename; Build a full catalog
