然后解压,将文件名修改为yii2-qrcode-helper放入vendor/2amigos/目录下面
编辑/vendor/yiisoft/extensions.php,添加以下代码到数组中
'2amigos/yii2-qrcode-helper' => array ( 'name' => '2amigos/yii2-qrcode-helper', 'version' => '1.0.2.0', 'alias' => array ( '@dosamigos/qrcode' => $vendorDir . '/2amigos/yii2-qrcode-helper/src', ), ),
用法
在你的控制器中添加一下代码
use dosamigos\qrcode\QrCode; //引入类 \\ ... public function actionQrcode() { return QrCode::png('http://www.yii-china.com'); //调用二维码生成方法 } public function actionDemo() { return $this->render('index'); }
在你的页面中添加以下代码 (demo/index)
<img src="/static/imghwm/default1.png" data-src="<?= Url::to(['index/qrcode'])? alt="Implementation code of Yii2.0 framework to generate QR code function" >" class="lazy" />

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.

PHP performance bottlenecks can be solved through the following steps: 1) Use Xdebug or Blackfire for performance analysis to find out the problem; 2) Optimize database queries and use caches, such as APCu; 3) Use efficient functions such as array_filter to optimize array operations; 4) Configure OPcache for bytecode cache; 5) Optimize the front-end, such as reducing HTTP requests and optimizing pictures; 6) Continuously monitor and optimize performance. Through these methods, the performance of PHP applications can be significantly improved.
