我們要生成二維碼都需要借助一些類庫來實現了,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來實現,不需要裝額外的php擴展,首先下載類庫包,有時候地址打不開,地址:http://phpqrcode.sourceforge.net/
下載:
國內下載:http://www.jb51.net/codes/189897.html
國外下載:http://sourceforge.net/projects/phpqrcode/
例子,使用PHP QR Code類庫創建二維碼。
1,浏覽器輸出:
<? include "phpqrcode/phpqrcode.php"; $value="http://www.jb51.net"; $errorCorrectionLevel = "L"; $matrixPointSize = "4"; QRcode::png($value, false, $errorCorrectionLevel, $matrixPointSize); exit; ?>
2,文件輸出二維碼
include('phpqrcode/phpqrcode.php'); // 二維碼數據 $data = 'http://www.jb51.net'; // 生成的文件名 $filename = '1111.png'; // 糾錯級別:L、M、Q、H $errorCorrectionLevel = 'L'; // 點的大小:1到10 $matrixPointSize = 4; QRcode::png($data, $filename, $errorCorrectionLevel, $matrixPointSize, 2);
3,生成中間帶logo的二維碼
<?php include('phpqrcode/phpqrcode.php'); $value='http://www.jb51.net'; $errorCorrectionLevel = 'L'; $matrixPointSize = 6; QRcode::png($value, 'xiangyang.png', $errorCorrectionLevel, $matrixPointSize, 2); echo "QR code generated"."<br />"; $logo = 'logo.png'; $QR = 'xiangyang.png'; if($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,'xiangyanglog.png'); ?>
