A PHP 7.4+ QR Code library based on the implementation by Kazuhiko Arase, namespaced, cleaned up, improved and other stuff.
See the wiki for advanced documentation. An API documentation created with phpDocumentor can be found at https://chillerlan.github.io/php-qrcode/ (WIP).
- PHP 7.4+
ext-mbstring
- optional:
ext-json
,ext-gd
ext-imagick
with ImageMagick installedsetasign/fpdf
for the PDF output module
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!
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" />';
Wait, what was that? Please again, slower! See Advanced usage on the wiki.

Hi, please check out my other projects that are way cooler than qrcodes!
- php-oauth-core - an OAuth 1/2 client library along with a bunch of providers
- php-httpinterface - a PSR-7/15/17/18 implemetation
- php-database - a database client & querybuilder for MySQL, Postgres, SQLite, MSSQL, Firebird
I don't take responsibility for molten CPUs, misled applications, failed log-ins etc.. Use at your own risk!
