php中用phpqrcode生成二维码，写好了生成二维码的QR.php,怎么引用这个让从前台中显示二维码，以下是QR.PHP里的代码，怎么引用呢，
<?php
require ('conn.php');
require ('functions.php');
// 指定允许其他域名访问
header ( 'Access-Control-Allow-Origin:*' );
include './phpqrcode/phpqrcode.php';
$date = date ( 'YmdHis', time () );
$uid = $_POST ['uid'];
// $value = 'http://' . $_SERVER ['HTTP_HOST'] . $_SERVER ['REQUEST_URI']; // 二维码内容
$domain = $mysql->query ( "select name from bat_shoutu_domain where status = 1" );
$value = "http://www.".$domain[0]['name']."/reg.php?uid=" . $uid;
$errorCorrectionLevel = 'L'; // 容错级别
$matrixPointSize = 4.55; // 生成图片大小
// 生成二维码图片
$QRCodeImg = "./static/QRCode/qrcode_1_$date.png"; // 已经生成的原始二维码图
QRcode::png ( $value, $QRCodeImg, $errorCorrectionLevel, $matrixPointSize, 2 );
$src_im = imagecreatefrompng ( $QRCodeImg );
$dst_im = imagecreatefromjpeg ( './static/index/hb.jpg' );
imagecopy ( $dst_im, $src_im, 220, 255, 0, 0, 150, 150 );
$dstImg = "./static/QRCode/qrcode_2_$date.png";
imagepng ( $dst_im, $dstImg );
$returnRst ["src"] = "qrcode_2_$date.png";
echo json_encode ( $returnRst );
?>
