QR Code in PHP

Technology keeps on growing. Nowadays in web everyone needs the QR code.

Brief on QR Code:

A QR code (abbreviated from Quick Response code) is a type of matrix barcode (or two-dimensional code) first designed for the automotive industry. More recently, the system has become popular outside of the industry due to its fast readability and comparatively large storage capacity. The code consists of black modules arranged in a square pattern on a white background. The information encoded can be made up of any kind of data (e.g., binary, alphanumeric, or Kanji symbols)

Eg: You convey message/Address/Phone etc., through QR code

Using PHP we can develop the QR code.

function generateQRwithGoogle($chl,$widhtHeight ='150',$EC_level='L',$margin='0') {
    echo '<img src="http://chart.apis.google.com/chart?chs='.$widhtHeight.
'&chl='.$chl.'" alt="QR code" widhtHeight="'.$widhtHeight.
'" widhtHeight="'.$widhtHeight.'"/>';
$urlToEncode = $_POST['urlToEncode'];
<form method="post" action="" name="ff1" id="ff1">
<input type="hidden" name="process" id="process" value="1">
QR encode: <input type="text" name="urlToEncode" id="urlToEncode" style="width:220px;"><input type="submit" name="Go" value="Go">
