Learn how to generate a QR code using PHP.
QR codes are two dimensional barcodes that can hold up to 2000 characters of text. Depending on the content, when you scan a QR code they can simply display the text they contain; open a browser at a specific URL, call a phone number and so on.
In the context of a web application, you might want to use them to link to an online invoice, a unique code for a ticket to gain entry to an event, a location on a map and so on.
