本文实例讲述了Laravel使用PHPQRCODE实现生成带有@R_404_395@的二维码图片功能。分享给大家供大家参考，具体如下：
input('type');//传递的类型 ios | android
require_once(dirname(__FILE__) . '/PHPqrcode/' . 'PHPqrcode.PHP');
$errorCorrectionLevel = 'H'; // 错误校正
$matrixPointSize = 5; // 边界空白位置
$QRcode = new \QRcode;
if($type){
if($type == 'ios'){
$value = 'http://www.ios.com'; // 二维码存放的内容
$QRcode->png($value,'ios.png',$errorCorrectionLevel,$matrixPointSize,2); //生成二维码
//echo "二维码已生成";
$@R_404_395@ = '@R_404_395@.png';//@R_404_395@的图片地址
//echo " 
";
$QR = 'ios.png'; //二维码图片地址
//echo " 
";
if($@R_404_395@ !== FALSE){
$QR = imagecreatefromstring(file_get_contents($QR));
$@R_404_395@ = imagecreatefromstring(file_get_contents($@R_404_395@));
$QR_width = imagesx($QR);
$QR_height = imagesy($QR);
$@R_404_395@_width = imagesx($@R_404_395@);
$@R_404_395@_height = imagesy($@R_404_395@);
$@R_404_395@_qr_width = $QR_width / 5;
$scale = $@R_404_395@_width / $@R_404_395@_qr_width;
$@R_404_395@_qr_height = $@R_404_395@_height / $scale;
$from_width = ($QR_width - $@R_404_395@_qr_width) / 2;
imagecopyresampled($QR,$@R_404_395@,$from_width,$@R_404_395@_qr_width,$@R_404_395@_qr_height,$@R_404_395@_width,$@R_404_395@_height);
}
imagepng($QR,'ios.png'); //跟@R_404_395@合并之后的地址
$a = 'http://www.ios.com/ios.png';
$status = 0;
$msg = $a;
}elseif($type == 'android'){
