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 ^4.2
  • 7.2+ use ^3.3
  • 7.0+ use ^2.0
  • 5.6+ use 1.0.9 (please let PHP 5 die!)

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! QR codes are awesome!

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

Framework Integration

Shameless advertising
