复制代码 代码如下:

<?php

$logo = isset($_GET['logo']) ? $_GET['logo'] :"./image/logo.jpg";

$chl = urlencode($logo);

$png = "http://chart.googleapis.com/chart?chs=$size&cht=qr&chl=$chl&chld=L|1&choe=UTF-8";

$QR = imagecreatefrompng($png);//外面那QR图

if ($logo !== FALSE) {

$logo = imagecreatefromstring(file_get_contents($logo));

$QR_width = imagesx($QR);

$QR_height = imagesy($QR);

$logo_width = imagesx($logo);

$logo_height = imagesy($logo);

$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);

}

header('Content-type: image/png');

imagepng($QR);

imagedestroy($QR);
