Documentation

See the wiki for advanced documentation. An API documentation created with phpDocumentor can be found at https://chillerlan.github.io/php-qrcode/ (WIP).

Requirements

  • PHP 7.4+
    • ext-mbstring
    • optional:

Installation

requires composer

via terminal: composer require chillerlan/php-qrcode

composer.json

{
	"require": {
		"php": "^7.4",
		"chillerlan/php-qrcode": "dev-main"
	}
}

Note: replace dev-main with a version constraint, e.g. ^3.2 - see releases for valid versions. For PHP version ...

  • 7.4+ use ^4.3
  • 7.2+ use ^3.4.1 (v3.4.1 also supports PHP8)
  • 7.0+ use ^2.0
  • 5.6+ use ^1.0 (please let PHP 5 die!)

In case you want to keep using dev-main, specify the hash of a commit to avoid running into unforseen issues like so: dev-main#b625396e0752d79747a55205ae7e191eeb459dcd

PSA: PHP 7.0 - 7.3 are EOL and therefore the respective QRCode versions are also no longer supported!

Quickstart

We want to encode this URI for a mobile authenticator into a QRcode image:

$data = 'otpauth://totp/test?secret=B3JX4VCVJDVNXNZ5&issuer=chillerlan.net';

// quick and simple:
echo '<img src="'.(new QRCode)->render($data).'" alt="QR Code" />';

QR codes are awesome!

Wait, what was that? Please again, slower! See Advanced usage on the wiki.

Framework Integration

Shameless advertising

Hi, please check out my other projects that are way cooler than qrcodes!
