/* 
 * Add those two lines of code to create a customized QR code. 
 * returns a graphic | with a default design | 300 dpi | PNG format.
 */
$QRcode = (new SoapClient('http://wsdl.qr-bot.de/',
                           array('local_cert' => "cert_key.pem",
                                 'encoding' => 'UTF-8')))->url('http://www.myurl.com',
                                                               'default','300','PNG');

/* Add this to display the QR code in the browser */
echo "";

Copy the cert on the server running the PHP code. Same folder as PHP script.
