php利用PHP QR Code生成二維碼(帶logo)
Jun 02, 2016 am 09:14 AM我們要生成二維碼都需要借助一些類(lèi)庫(kù)來(lái)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(jiǎn)單,下面我來(lái)介紹一下。
利用php類(lèi)庫(kù)PHP QR Code來(lái)實(shí)現(xiàn),不需要裝額外的php擴(kuò)展
首先下載類(lèi)庫(kù)包,有時(shí)候地址打不開(kāi)
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('phpqrcode/phpqrcode.php'); // 二維碼數(shù)據(jù) $data = 'http://www.phprm.com'; // 生成的文件名 $filename = '1111.png'; // 糾錯(cuò)級(jí)別:L、M、Q、H $errorCorrectionLevel = 'L'; // 點(diǎn)的大?。?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('phpqrcode/phpqrcode.php'); $value='http://www.phprm.com'; $errorCorrectionLevel = 'L'; $matrixPointSize = 10; QRcode::png($value, 'xiangyang.png', $errorCorrectionLevel, $matrixPointSize, 2); echo "QR code generated"."<br />"; $logo = 'bdlogo.gif'; $QR = 'xiangyang.png'; if($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'); ?>
