php利用PHP QR Code生成二维码(带logo)

<?php
    include "phpqrcode/phpqrcode.php";
    $value="http://www.hzhuti.com";
    $errorCorrectionLevel = "L";
    $matrixPointSize = "4";
    QRcode::png($value, false, $errorCorrectionLevel, $matrixPointSize);
    exit;
?>

//文件输出
    include('phpqrcode/phpqrcode.php');
   
// 二维码数据
    $data = 'http://www.111cn.net';
   
// 生成的文件名
    $filename = '1111.png';
   
// 纠错级别：L、M、Q、H
    $errorCorrectionLevel = 'L';
   
// 点的大小：1到10
    $matrixPointSize = 4;
    QRcode::png($data, $filename, $errorCorrectionLevel, $matrixPointSize, 2);

<?php
   
//生成中间带logo的二维码
