Generate QR Code in PHP with PHP QR Code Generator source code

A QR code (abbreviated from Quick Response code) is a type of matrix bar-code (or two-dimensional code) first designed for the automotive industry. More recently, the system has become popular outside of the automotive 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).


The amount of data that can be stored in the QR code depends on the character set, version and error correction level. The maximum values for version 40 with error correction capacity levels L, M, Q and H are:

Numeric only 7,089 5,596 3,993 3,057
Alphanumeric 4,296 characters 3,391 characters 2,420 characters 1,852 characters
Binary (8 bits) 2,953 bytes 2,331 bytes 1,663 bytes 1,273 bytes
