yii生成二维码新版

首先需要安装qrcode最新 yii插件：

php composer.phar require 2amigos/qrcode-library:~1.1

调用方式：

use Da\QrCode\QrCode;


$qrCode = (new QrCode(‘This is my text’))

->setSize(250)
->setMargin(5)
->useForegroundColor(51, 153, 255);


// now we can display the qrcode in many ways
// saving the result to a file:

$qrCode->writeFile(DIR . ‘/code.png’); // writer defaults to PNG when none is specified

// display directly to the browser
header(‘Content-Type: ‘.\(qrCode->getContentType());
echo \)qrCode->writeString();
