If you have read my earlier posts, you must have seen that I am excited about implementing QR Code to my projects. These mostly include my work projects.
Today I have discovered that Fukuchi Kentaro, who is an assistant professor has written a very useful QR Code library to use on UNIX based systems. I have immediately downloaded the library and compiled it. It ran smoothly on my server, so I created a little PHP function to use with this library, for real time QR Code generation.
I have put a page on my server for you to use the function. You can call that page supplying a base64 encoded URL and it will create a QR Code PNG on the fly.
This is a demonstration of calling the page:
http://www.keremerkan.net/qrcode/qr.php?c=aHR0cDovL2tlcmVtZXJrYW4ubmV0Lwo=
UPDATE: The page gets redirected to PHP QR Code Generator page on this blog now.
aHR0cDovL2tlcmVtZXJrYW4ubmV0Lwo= is Base64 encoded presentation of my blog URL, http://keremerkan.net/
You can easily Base64 encode this string by executing the command below from a UNIX shell:
echo http://keremerkan.net/ | openssl enc -base64
The function will only accept Base64 encoded URLs to avoid some nasty side effects. Also after decoding the URL, there should be no dangerous characters like ‘,!,<,> in the URL.
By calling the page like I gave above, you will get the image below (It is auto generated):
To read this image from your phone, you will need a QR Code reader installed on your mobile phone. You can get a QR Code reader from QuickMark or Kaywa sites for free. (PS: Kaywa reader needs you to register for download)
