How To Generate QR Code In PHP Example
In this blog, I will learn you generating a QR code using PHP.
There are a number of open source libraries available online which can be acclimated to engender a Quick Response(QR) Code. A good open source library for QR code generation in PHP is available in sourceforge. It just needs to be downloaded and replicated in the project folder. This includes a module denominated “phpqrcode” in which there is a file denominated “qrlib.php”. This file must be included in the code to utilize a function denominated ‘png()’, which is inside QRcode class. png() function outputs directly a QR code in the browser when we pass some text as a parameter, but we can also engender a file and store it.Syntax:
QRcode::png($text, $file, $ecc, $pixel_Size, $frame_Size);
Parameters: This function accepts five parameters as mentioned above and described below:
- $text - This parameter gives the message which needs to be in QR code. It is mandatory parameter.
- $file - It specifies the place to save the generated QR.
- $ecc - This parameter specifies the error correction capability of QR. It has 4 levels L, M, Q and H.
- $pixel_Size - This specifies the pixel size of QR.
- $frame_Size - This specifies the size of Qr. It is from level 1-10.
<?php // Include the qrlib file include 'phpqrcode/qrlib.php'; // $text variable has data for QR $text = "Welcome To MyWebtuts.com"; // QR Code generation using png() // When this function has only the // text parameter it directly // outputs QR in the browser QRcode::png($text); ?>
Example : 2
<?php //Include the necessary library for Ubuntu include('phpqrcode/qrlib.php'); //Set the data for QR $text = "https://www.mywebtuts.com/"; //Set the filename with unique id $filename = uniqid().".png"; //Set the error correction Level('L') $e_correction = 'L'; //Set pixel size $pixel_size = 12; //Set the frame size $frame_size = 8; //Generates QR image QRcode::png($text, $filename, $e_correction, $pixel_size, $frame_size); //Display the QR image echo ""; ?>
