Simple Quick Response (QR) Code Generator Web App Using PHP QR CODE Library With Source Code


This is a simple project that has a Quick Response Code Generator in PHP with the use of PHP QR Code Library. This project's purpose is to share this with the IT/CS students or self-learners to give an idea of how to create a web app that generates a QR Code. The source code has only a minimum scope which only has a simple form that has 3 text/input fields. The fields are the email, subject, and message. These fields will be used for generating a Quick Response Code.


  • Simple Form
  • Generated Quick Response Field
  • Download QR Code as a PNG Format.

Plugins/Libraries Used

  • Bootstrap 3.3.7

How the App Works

To generate a Quick Response (QR) Code, the user must fill first all text or input fields provided in the form. After that, when the user will submit the form, the Generated Quick Response Code will be shown on the right side of the screen. The expected text format of the generated QR Code is "mailto:{email}?subject={subject}&body={message}" (i.e. [mailto:[email protected]?subject=Test&body=Hello+World]). Click the Download button below the Generated QR Code to download the code into PNG Format.

Note: Due to the size or complexity of this submission, the author has submitted it as a .zip file to shorten your download time. After downloading it, you will need a program like Winzip to decompress it.

Virus note: All files are scanned once-a-day by for viruses, but new viruses come out every day, so no prevention program can catch 100% of them.


1. Re-scan downloaded files using your personal virus checker before using it.
2. NEVER, EVER run compiled files (.exe's, .ocx's, .dll's etc.)--only run source code.

Please attach the index.php file cos the embedded is empty

In what part of my code does index.php is missing? Actually, index.php is there, in every directory. But there is no code written on it. It's purpose is just to hide the folders content from web browsers.
