PHP生成带LOGO的二维码,或许很多高手都已经实现了,但之前并没有过多关注这方面,这段有个小项目要用到二维码生成,索引就查了些资料,发些有一个PHP 类库phpqrcode对生成这种二维码很方便,索引就测试了一下,下面把自己的用法和代码与菜鸟分享,希望高手鼓励哦。
首先你需要下载这个类库包,或者我后边会附上这个类库,具体的使用代码:
<?php //文件输出 include(‘phpqrcode.php‘); // 二维码数据 $data = ‘http://www.codesc.net‘; // 生成的文件名 $filename = ‘ewm.png‘; // 纠错级别:L、M、Q、H $errorCorrectionLevel = ‘L‘; // 点的大小:1到10 $matrixPointSize = 4; QRcode::png($data, $filename, $errorCorrectionLevel, $matrixPointSize, 2); ?>
<?php include (‘phpqrcode.php‘); $value = ‘http://www.codesc.net‘; $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‘ ); ?>
