Hi I would like to scann a Qr code in a PHP web application with a smartphone camera but I don't find how .
I have tried this

with this link
zxing://scan/?ret={CODE}&q={CODE}&SCAN_FORMATS=UPC_A,EAN_13
But ret={CODE} don't works . How to get to link my QR code remaining in the same window of my browser or what alternative is there?
