ThinkPHP3.2.3扩展之二维码，thinkphp3.2.3扩展

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.
