title: QR Barcode image back to text
body: <p>I've converted <code>hello world</code> to QR Barcode image but my question is about getting the text back.</p>
  <p><img src="https://i.stack.imgur.com/pQV0s.png" alt="enter image description here" /></p>
  <p>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?!</p>
  <p>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?!</p>
