QR Barcode image back to text

I've converted hello world to QR Barcode image but my question is about getting the text back.

enter image description here

I mean if I sent that image to my friend, then is there any way that my friend get it back to text without using mobile reader/barcode reader machine .etc. so is there any PHP function can do this?!

If not then is there any idea I can convert text to encoded image then with PHP function whatever! I can get it back to text?!

Solution

  • There are several web based QR decoders. Your friend can just upload the image and the service will tell her what the code says.

    One of the most popular is ZXing - http://zxing.org/w/decode.jspx
