Dynamically generating a QR code with PHP

I'm trying to generate QR codes on my website. All they have to do is have a URL in them, which a variable on my site will provide. What would be the easiest way to do this?

Solution

  • THIS NO LONGER WORKS

    It's worth adding that, in addition to the QR codes library posted by @abaumg, Google provides a QR Codes API QR Codes APImany thanks to @Toukakoukan for the link update.

    To use this, basically:

    https://chart.googleapis.com/chart?chs=300x300&cht=qr&chl=http%3A%2F%2Fwww.google.com%2F&choe=UTF-8
    • 300x300 is the size of the QR image you want to generate,
    • the chl is the url-encoded string you want to change into a QR code, and
    • the choe is the (optional) encoding.

    The link, above, gives more detail, but to use it just have the src of an image point to the manipulated value, like so:

    <img src="https://chart.googleapis.com/chart?chs=300x300&cht=qr&chl=http%3A%2F%2Fwww.google.com%2F&choe=UTF-8" title="Link to Google.com" />
