title: Scanning and storing data in PHP using QR code
body: <p>i'm working on a project for scanning QR codes for student attendance. Currently i'm able to generate the QR code but scanning the QR code and storing the data of QR code makes me confused. Is there any advice or reference that I could follow? I'm using PHP, WAMP Server, MySQL and CodeIgniter framework. The QR Code library i'm using is from <a href="https://github.com/dwisetiyadi/CodeIgniter-PHP-QR-Code" rel="nofollow noreferrer">github code</a> to generate the QR's.</p>
