简单使用无logo:
- public function qrcode(){
- Vendor('phpqrcode.phpqrcode');
- //生成二维码图片
- $object = new \QRcode();
- $url='http://www.shouce.ren/';//网址或者是文本内容
- $level=3;
- $size=4;
- $errorCorrectionLevel =intval($level) ;//容错级别
- $matrixPointSize = intval($size);//生成图片大小
- $object->png($url, false, $errorCorrectionLevel, $matrixPointSize, 2);
- }
高级使用带logo:
- public function qrcode(){
- Vendor('phpqrcode.phpqrcode');
- //生成二维码图片
- $object = new \QRcode();
- $qrcode_path='';
- $file_tmp_name='';
- $errors=array();
- if(!empty($_POST)){
- $content = trim($_POST['content']); //二维码内容
- $contentSize=$this->getStringLength($content);
- if($contentSize>150){
- $errors[]='字数过长,不能多于150个字符!';
- }
- if(isset($_FILES['upimage']['tmp_name']) && $_FILES['upimage']['tmp_name'] && is_uploaded_file($_FILES['upimage']['tmp_name'])){
- if($_FILES['upimage']['size']>512000){
- $errors[]="你上传的文件过大,最大不能超过500K。";
- }
- $file_tmp_name=$_FILES['upimage']['tmp_name'];
- $fileext = array("image/pjpeg","image/jpeg","image/gif","image/x-png","image/png");
- if(!in_array($_FILES['upimage']['type'],$fileext)){
- $errors[]="你上传的文件格式不正确,仅支持 png, jpg, gif格式。";
- }
- }
- $tpgs=$_POST['tpgs'];//图片格式
- $qrcode_bas_path='upload/qrcode/';
- if(!is_dir($qrcode_bas_path)){
- mkdir($qrcode_bas_path, 0777, true);
- }
- $uniqid_rand=date("Ymdhis").uniqid(). rand(1,1000);
- $qrcode_path=$qrcode_bas_path.$uniqid_rand. "_1.".$tpgs;//原始图片路径
- $qrcode_path_new=$qrcode_bas_path.$uniqid_rand."_2.".$tpgs;//二维码图片路径
- if(Helper::getOS()=='Linux'){
- $mv = move_uploaded_file($file_tmp_name, $qrcode_path);
- }else{
- //解决windows下中文文件名乱码的问题
- $save_path = Helper::safeEncoding($qrcode_path,'GB2312');
- if(!$save_path){
- $errors[]='上传失败,请重试!';
- }
- $mv = move_uploaded_file($file_tmp_name, $qrcode_path);
- }
- if(empty($errors)){
- $errorCorrectionLevel = $_POST['errorCorrectionLevel'];//容错级别
- $matrixPointSize = $_POST['matrixPointSize'];//生成图片大小
- $matrixMarginSize = $_POST['matrixMarginSize'];//边距大小
- //生成二维码图片
- $object::png($content,$qrcode_path_new, $errorCorrectionLevel, $matrixPointSize, $matrixMarginSize);
- $QR = $qrcode_path_new;//已经生成的原始二维码图
- $logo = $qrcode_path;//准备好的logo图片
- if (file_exists($logo)) {
- $QR = imagecreatefromstring(file_get_contents($QR));
- $logo = imagecreatefromstring(file_get_contents($logo));
- $QR_width = imagesx($QR);//二维码图片宽度
- $QR_height = imagesy($QR);//二维码图片高度
- $logo_width = imagesx($logo);//logo图片宽度
- $logo_height = imagesy($logo);//logo图片高度
- $logo_qr_width = $QR_width / 5;
- $scale = $logo_width/$logo_qr_width;
- $logo_qr_height = $logo_height/$scale;
- $from_width = ($QR_width - $logo_qr_width) / 2;
- //重新组合图片并调整大小
- imagecopyresampled($QR, $logo, $from_width, $from_width, 0, 0, $logo_qr_width,
- $logo_qr_height, $logo_width, $logo_height);
- //输出图片
- //header("Content-type: image/png");
- imagepng($QR,$qrcode_path);
- imagedestroy($QR);
- }else{
- $qrcode_path=$qrcode_path_new;
- }
- }else{
- $qrcode_path='';
- }
- }
- $data=array('data'=>array('errors'=>$errors,'qrcode_path'=>$qrcode_path));
- $this->assign('data',$data);
- $this->display();
