How to upload images and generate thumbnails in thinkphp5
下面为大家分享一篇thinkphp5上传图片及生成缩略图公共方法,具有很好的参考价值,希望对大家有所帮助。
直接上代码,可以写在公共文件common和继承的基础类中,方便调用
/* * $name为表单上传的name值 * $filePath为为保存在入口文件夹public下面uploads/下面的文件夹名称,没有的话会自动创建 * $width指定缩略宽度 * $height指定缩略高度 * 自动生成的缩略图保存在$filePath文件夹下面的thumb文件夹里,自动创建 * @return array 一个是图片路径,一个是缩略图路径,如下: * array(2) { ["img"] => string(57) "uploads/img/20171211\3d4ca4098a8fb0f90e5f53fd7cd71535.jpg" ["thumb_img"] => string(63) "uploads/img/thumb/20171211/3d4ca4098a8fb0f90e5f53fd7cd71535.jpg" } */ protected function uploadFile($name,$filePath,$width,$height) { $file = request()->file($name); if($file){ $filePaths = ROOT_PATH . 'public' . DS . 'uploads' . DS .$filePath; if(!file_exists($filePaths)){ mkdir($filePaths,0777,true); } $info = $file->move($filePaths); if($info){ $imgpath = 'uploads/'.$filePath.'/'.$info->getSaveName(); $image = \think\Image::open($imgpath); $date_path = 'uploads/'.$filePath.'/thumb/'.date('Ymd'); if(!file_exists($date_path)){ mkdir($date_path,0777,true); } $thumb_path = $date_path.'/'.$info->getFilename(); $image->thumb($width, $height)->save($thumb_path); $data['img'] = $imgpath; $data['thumb_img'] = $thumb_path; return $data; }else{ // 上传失败获取错误信息 return $file->getError(); } } }

Session in PHP is a mechanism for saving user data on the server side to maintain state between multiple requests. Specifically, 1) the session is started by the session_start() function, and data is stored and read through the $_SESSION super global array; 2) the session data is stored in the server's temporary files by default, but can be optimized through database or memory storage; 3) the session can be used to realize user login status tracking and shopping cart management functions; 4) Pay attention to the secure transmission and performance optimization of the session to ensure the security and efficiency of the application.

Absolute session timeout starts at the time of session creation, while an idle session timeout starts at the time of user's no operation. Absolute session timeout is suitable for scenarios where strict control of the session life cycle is required, such as financial applications; idle session timeout is suitable for applications that want users to keep their session active for a long time, such as social media.

The server session failure can be solved through the following steps: 1. Check the server configuration to ensure that the session is set correctly. 2. Verify client cookies, confirm that the browser supports it and send it correctly. 3. Check session storage services, such as Redis, to ensure that they are running normally. 4. Review the application code to ensure the correct session logic. Through these steps, conversation problems can be effectively diagnosed and repaired and user experience can be improved.

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
