我们要生成二维码都需要借助一些类库来实现了,下面我介绍利用PHP QR Code生成二维码吧,生成方法很简单,下面我来介绍一下。

利用php类库PHP QR Code来实现,不需要装额外的php扩展

首先下载类库包,有时候地址打不开

地址:http://phpqrcode.sourceforge.net/

下载:http://sourceforge.net/projects/phpqrcode/

使用时一般引入phpqrcode.php文件即可

具体使用方法举例

直接浏览器输出:

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

图片文件输出

<?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); 
?>
Copy after login

生成中间带logo的二维码

<?php 
    
//生成中间带logo的二维码 
    include(&#39;phpqrcode/phpqrcode.php&#39;); 
    $value=&#39;http://www.phprm.com&#39;; 
    $errorCorrectionLevel = &#39;L&#39;; 
    $matrixPointSize = 10; 
    QRcode::png($value, &#39;xiangyang.png&#39;, $errorCorrectionLevel, $matrixPointSize, 2); 
    echo "QR code generated"."<br />"; 
    $logo = &#39;bdlogo.gif&#39;; 
    $QR = &#39;xiangyang.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;xiangyanglog.png&#39;); 
?>
Copy after login
