This article mainly introduces Laravel to use PHPQRCODE to realize the function of generating QR code images with LOGO. It involves the relevant calling and setting operation skills of introducing the PHPQRCODE class into php to generate QR code images. Friends who need it can refer to it. I hope it can Help everyone.


/**
* 利用phpqrcode来实现生成带有logo的二维码图片
*/
public function getQrCode(Request $request){
    $type  =  $request->input('type');//传递的类型 ios | android
    require_once(dirname(__FILE__) . '/phpqrcode/' . 'phpqrcode.php');
    $errorCorrectionLevel = 'H'; // 错误校正
    $matrixPointSize = 5; // 边界空白位置
    $QRcode =  new \QRcode;
    if($type){
      if($type == 'ios'){
        $value =  'http://www.ios.com'; // 二维码存放的内容
        $QRcode->png($value, 'ios.png', $errorCorrectionLevel, $matrixPointSize, 2); //生成二维码
        //echo "二维码已生成";
        $logo = 'logo.png';//logo的图片地址
        //echo " <img src=&#39;../../../public/logo.png&#39;>";
        $QR = &#39;ios.png&#39;; //二维码图片地址
        //echo " <img src=&#39;../../../ios.png&#39;>";
        if($logo !== FALSE){
          $QR = imagecreatefromstring(file_get_contents($QR));
          $logo = imagecreatefromstring(file_get_contents($logo));
          $QR_width = imagesx($QR);
          $QR_height = imagesy($QR);
          $logo_width = imagesx($logo);
          $logo_height = imagesy($logo);
          $logo_qr_width = $QR_width / 5;
          $scale = $logo_width / $logo_qr_width;
          $logo_qr_height = $logo_height / $scale;
          $from_width = ($QR_width - $logo_qr_width) / 2;
          imagecopyresampled($QR, $logo, $from_width, $from_width, 0, 0, $logo_qr_width, $logo_qr_height, $logo_width, $logo_height);
        }
        imagepng($QR,&#39;ios.png&#39;); //跟logo合并之后的地址
        $a   =  &#39;http://www.ios.com/ios.png&#39;;
        $status =  0;
        $msg  =  $a;
      }elseif($type == &#39;android&#39;){
          $value =  &#39;http://www.android.com&#39;; // 二维码存放的内容
          //var_dump($value);
          $QRcode->png($value, &#39;android.png&#39;, $errorCorrectionLevel, $matrixPointSize, 2); //生成二维码
          //echo "二维码已生成";
          $logo = &#39;logo.png&#39;;//logo的图片地址
          //echo " <img src=&#39;../../../public/logo.png&#39;>";
          $QR = &#39;android.png&#39;; //二维码图片地址
          //echo " <img src=&#39;../../../android.png&#39;>";
          if($logo !== FALSE){
            $QR = imagecreatefromstring(file_get_contents($QR));
            $logo = imagecreatefromstring(file_get_contents($logo));
            $QR_width = imagesx($QR);
            $QR_height = imagesy($QR);
            $logo_width = imagesx($logo);
            $logo_height = imagesy($logo);
            $logo_qr_width = $QR_width / 5;
            $scale = $logo_width / $logo_qr_width;
            $logo_qr_height = $logo_height / $scale;
            $from_width = ($QR_width - $logo_qr_width) / 2;
            imagecopyresampled($QR, $logo, $from_width, $from_width, 0, 0, $logo_qr_width, $logo_qr_height, $logo_width, $logo_height);
          }
          imagepng($QR,&#39;android.png&#39;); //跟logo合并之后的地址
          $a   =  &#39;http://www.android.com/android.png&#39;;
          $status =  0;
          $msg  =  $a;
      }else{
        $status =  1;
        $msg  =  &#39;没有该类型!&#39;;
      }
      //QRcode::png($value, &#39;sunny.png&#39;, $errorCorrectionLevel, $matrixPointSize, 2); //生成二维码
    }else{
      $status =  2;
      $msg  =  &#39;参数传递不完整!&#39;;
    }
    return response()->json([&#39;status&#39; => $status,&#39;msg&#39; => $msg])->header(&#39;Access-Control-Allow-Origin&#39;, &#39;*&#39;);
