一个二维码封装的thinkphp函数
Qrcode 类为开源生成的类 在 vendor目录下
需要注意的是时间每天生成的二维码 都放在当天的文件夹下 切记
[php]
// 二维码函数
function qrcode($value,$errorCorrectionLevel, $matrixPointSize){
vendor('Qrcode.qrlib');
//$value 传入的值
//$filename 文件名称
//$errorCorrectionLevel 类型：L M Q H；
//$matrixPointSize 大小 1 2 3 4 5 6 7 8 9 10 中的一个
//$info=QRcode::png($value,$filename,$errorCorrectionLevel, $matrixPointSize, 2);
// $PNG_TEMP_DIR ='/Upload/'.'Qrcode'.'/';
//根据时间创建目录 每天创建一个
$time=date("Ymd",time());

//html PNG location prefix
//$now=strtotime($time);
//dump($time);

//include "qrlib.php";
//ofcourse we need rights to create temp dir
if (!file_exists($PNG_TEMP_DIR))

//remember to sanitize user input in real-life solution !!!
