License: Apache License 2.0
Languages: PHP, PostScript, Twig
A PHP QR Code generator based on the implementation by Kazuhiko Arase, namespaced, cleaned up, improved and other stuff.
It also features a QR Code reader based on a PHP port of the ZXing library.
Hi! Please check out the v5.0-beta release and leave your feedback in this discussion thread. Thanks!
Attention: there is now also a javascript port: chillerlan/js-qrcode.
ext-mbstring
ext-fileinfo
(required by QRImagick
output)ext-gd
ext-imagick
with ImageMagick installedsetasign/fpdf
for the PDF output moduleFor the QRCode reader, either ext-gd
or ext-imagick
is required!
QROptions
container can be found here: chillerlan/php-settings-containerSee the installation guide for more info!
composer require chillerlan/php-qrcode
{
"require": {
"php": "^7.4 || ^8.0",
"chillerlan/php-qrcode": "dev-main#<commit_hash>"
}
}
Note: replace dev-main
with a version constraint, e.g. ^4.3
- see releases for valid versions.
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 in the manual. Also, have a look in the examples folder for some more usage examples.
Using the built-in QR Code reader is pretty straight-forward:
// it's generally a good idea to wrap the reader in a try/catch block because it WILL throw eventually
try{
$result = (new QRCode)->readFromFile('path/to/file.png'); // -> DecoderResult
// you can now use the result instance...
$content = $result->data;
$matrix = $result->getMatrix(); // -> QRMatrix
// ...or simply cast it to string to get the content:
$content = (string)$result;
}
catch(Throwable $e){
// oopsies!
}
Hi, please check out some of my other projects that are way cooler than qrcodes!
I don't take responsibility for molten CPUs, misled applications, failed log-ins etc.. Use at your own risk!
