Dynamically generating a QR code using PHP:
There are a number of open source libraries available online which can be used to generate a Quick Response(QR) Code.

A good open-source library for QR code generation in PHP is available in SourceForge. It just needs to be downloaded and copied into the project folder. This includes a module named “phpqrcode” in which there is a file named “qrlib.php”. This file must be included in the code to use a function named ‘png()’, which is inside the QRcode class. png() function outputs directly a QR code in the browser when we pass some text as a parameter, but we can also create a file and store it.
