// ==============php phpqrcode 生成二维码======================== |
// 下载地址：http://sourceforge.net/projects/phpqrcode/files/latest/download |
// 只需要包含 phpqrcode.php 文件就可以。 |
|
// 一：直接输出 |
include "./phpqrcode.php"; |
$value="http://www.useryx.com"; |
$errorCorrectionLevel = "L"; // 纠错级别：L、M、Q、H |
$matrixPointSize = "4"; // 点的大小：1到10 |
QRcode::png($value, false, $errorCorrectionLevel, $matrixPointSize); |
|
|
// 二：图片文件输出 |
include('./phpqrcode.php'); |
$data = 'http://www.useryx.com'; |
$filename = 'useryx.png'; // 生成的文件名 |
$errorCorrectionLevel = 'L'; // 纠错级别：L、M、Q、H |
$matrixPointSize = 4; // 点的大小：1到10 |
QRcode::png($data, $filename, $errorCorrectionLevel, $matrixPointSize, 2); |
|
|
//三： 生成中间带logo的二维码 |
include('./phpqrcode.php'); |
$value='http://www.useryx.com'; |
$logo = 'logo.jpg'; // 中间的logo |
$QR = "base.png"; // 自定义生成的。结束后可以删除 |
$last = "last.png"; // 最终生成的图片 |
$errorCorrectionLevel = 'L'; |
$matrixPointSize = 10; |
QRcode::png($value, $QR, $errorCorrectionLevel, $matrixPointSize, 2); |
if($logo !== FALSE){ |
