Generating QR Code Using PHP
A good open-source library for QR code generation in PHP is available in sourceforge.
- It just needs to be downloaded and copied into the project folder.
- This includes a module named “phpqrcode” in which there is a file named “qrlib.php”.
- This file must be included in the code to use a function named ‘png()’, which is inside the QRcode class. png() function outputs directly a QR code in the browser when we pass some text as a parameter, but we can also create a file and store it.
Code:
<?php
// Include the qrlib file
include 'phpqrcode/qrlib.php';
$data["data"]["asset_number"]=$asset_number;
$data["type"]="asset_data";
$path = 'temp_upload/asset_qrcodes/';
$file = $path.uniqid().".png";
// Generates QR Code and Stores it in the directory given
QRcode::png(json_encode($data), $file,QR_ECLEVEL_L,10,0);
// Displaying the stored QR code from the directory
echo "<center><img src='https://erp.gengroup.in/$file'></center>";
echo "</br>";
echo "<center><h2>$asset_number</h2></center>";
