       6  * This file contains MERGED version of PHP QR Code library.
       7  * It was auto-generated from full version for your convenience.
       8  *
       9  * This merged version was configured to not requre any external files,
      10  * with disabled cache, error loging and weker but faster mask matching.
      11  * If you need tune it up please use non-merged version.
      12  *

    调用产生图片

    <?php
    //引入核心库文件
    require_once('phpqrcode.php');
    
    //定义纠错级别
    
    $errorLevel = "L";
    
    //定义生成图片宽度和高度;默认为3
    
    $size = "6";
    
    //定义生成内容
    
    // $content="尝试一下内容测试";
    // //调用QRcode类的静态方法png生成二维码图片//
    
    // QRcode::png($content, false, $errorLevel, $size);
    
    //生成网址类型
    
    $url="http://47.92.74.202:90/login.php?id=mn0201";
    
    
    
    QRcode::png($url, false, $errorLevel, $size);
