先安照路径放好如图。

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();
