This is PHP 7+ only implementation of QR Code 2-D barcode generator.

Based on:
http://sourceforge.net/projects/phpqrcode/
By Dominik Dzienia

I was looking for a QR implementation for the pChart fork and came across this one.
It was either refactor Dominik's or use Chillerlan's (https://github.com/chillerlan/php-qrcode)
This fork is not a drop in replacement.
My code is four times smaller and two times faster
(much much faster than the Chillerlan's implementation)

Usage:

Possible hints: "Numeric", "Alphanumeric", "Byte", "Kanji"

• Single line:
  

(new QRCode([

'level' => $error_correction_level,

'size' => $max_module_size,

'margin' => $white_frame_size

]))->encode('https://github.com/zhangchunsheng/php-qrcode')->toFile("example.QRcode.png");

• Or:
  $QRCode = new QRCode(['level' => "Q", 'size' => 10, 'margin' => 4]);
  $QRCode->encode('https://github.com/zhangchunsheng/php-qrcode', $hint);
  

• Dump the matrix:
  echo json_encode($QRCode->toArray());
  

• Load a matrix:
  $QRCode->fromArray($matix);
  

• Dump base64 encoded PNG:
  $QRCode->toBase64();
  

• Create ASCII:
  $QRCode->toASCII();
  

• Output to file:
  $QRCode->toFile("example.QRcode.png");
  $QRCode->toFile("example.QRcode.svg");
  $QRCode->toFile("example.QRcode.jpg");
  

• Add HTTP headers:
  $QRCode->forWeb("PNG");
  $QRCode->forWeb("SVG");
  $QRCode->forWeb("JPG", $quality = 90);
