​Please include the following things:

  • CV (or links to your online profile (LinkedIn, Xing, Twitter, Blog, Websites)

  • Testcase Code (if you have no Zend Framework code examples)

Test Case: “QR code render function

  • We expect clean, well documented (DocBlocks) code in the same way Zend Framework is built and documented.
  • We like to see (abstract) classes, methods, interfaces, exceptions (SPL: http://php.net/manual/en/spl.exceptions.php) and constants the way they should be used.
  • If you want to go the extra mile include something that shows us you’ve got skills. You could also write a few paragraphs to outline your design decisions.
  • Your solution should be self-contained. You are only allowed to use dependencies (like a 3rd party HTTP client) if you provide a composer.json (http://getcomposer.org).


Write an object-oriented QR code renderer where the renderer logic can be switched/injected. As a reference and default implementation use https://developers.google.com/chart/infographics/docs/qr_codes.


The API should look like this:


use yournamespaceQrCode,


$qrCode = new QrCode('TrekkSoft', 50, 50); // text, width, height

$qrCode->setRenderer(new GoogleChartsRenderer());

$qrCodeData = $qrCode->generate(); // should return the image data, not the URL
