php利用PHP QR Code生成二维码(带logo)

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

<?php 
    
//文件输出 
    include(&#39;phpqrcode/phpqrcode.php&#39;); 
    
// 二维码数据 
    $data = &#39;http://www.phprm.com&#39;; 
    
// 生成的文件名 
    $filename = &#39;1111.png&#39;; 
    
// 纠错级别：L、M、Q、H 
    $errorCorrectionLevel = &#39;L&#39;; 
    
// 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
