我們要生成二維碼都需要借助一些類庫來實(shí)現(xiàn)了,下面我介紹利用PHP QR Code生成二維碼吧,生成方法很簡單,下面我來介紹一下。

利用php類庫PHP QR Code來實(shí)現(xiàn),不需要裝額外的php擴(kuò)展

首先下載類庫包,有時(shí)候地址打不開

地址:http://phpqrcode.sourceforge.net/

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

使用時(shí)一般引入phpqrcode.php文件即可

具體使用方法舉例

直接瀏覽器輸出:

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

圖片文件輸出

<?php 
    
//文件輸出 
    include(&#39;phpqrcode/phpqrcode.php&#39;); 
    
// 二維碼數(shù)據(jù) 
    $data = &#39;http://www.phprm.com&#39;; 
    
// 生成的文件名 
    $filename = &#39;1111.png&#39;; 
    
// 糾錯(cuò)級(jí)別:L、M、Q、H 
    $errorCorrectionLevel = &#39;L&#39;; 
    
// 點(diǎn)的大小:1到10 
    $matrixPointSize = 4; 
    QRcode::png($data, $filename, $errorCorrectionLevel, $matrixPointSize, 2); 
?>

生成中間帶logo的二維碼

<?php 
    
//生成中間帶logo的二維碼 
    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;); 
?>
