This article mainly shares with you examples of how to implement multiple file uploads in php3.2. I hope it can help you.
public function upload(){ $upload = new \Think\Upload();// 实例化上传类 $upload->maxSize = 3145728 ;// 设置附件上传大小 $upload->exts = array('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型 $upload->rootPath = './Uploads/'; // 设置附件上传根目录 $upload->savePath = 'slider/'; // 设置附件上传(子)目录 // 上传单个文件 $info = $upload->uploadOne($_FILES['files']); if(!$info) {// 上传错误提示错误信息 $this->error($upload->getError()); }else{// 上传成功 获取上传文件信息 $url= $info['savepath'].$info['savename']; } return $url; }
This is the source code when uploading a single file, in which $info = $upload->uploadOne($_FILES['files']); This position limits the file upload to a single file
There is also the issue of front-end input selection
public function upload(){ $upload = new \Think\Upload();// 实例化上传类 $upload->maxSize = 3145728 ;// 设置附件上传大小 $upload->exts = array('jpg', 'gif', 'png', 'jpeg');// 设置附件上传类型 $upload->rootPath = './Uploads/'; // 设置附件上传根目录 $upload->savePath = 'last/'; // 设置附件上传(子)目录 // 上传多个文件 $info = $upload->upload(); if(!$info) {// 上传错误提示错误信息 $this->error($upload->getError()); }else{// 上传成功 获取上传文件信息 foreach($info as $file){ $url .= $file['savepath'].$file['savename'].','; } } return $url; }
This is a multi-file upload method. The main difference is $info = $upload->upload();This part
And $url .= $file['savepath'].$file['savename'].','; The limitations of this part
The difference between single file and multiple files on the front end is also very big
This is the difference between multiple files
<input type="file" name="files[]" multiple="">
Official explanation
If you need to upload multiple files, you only need to modify the form and change
<input type='file' name='photo'>
to ## The file upload classes of the two methods of #
<input type='file' name='photo1'> <input type='file' name='photo2'> <input type='file' name='photo3'>or
<input type='file' name='photo[]'> <input type='file' name='photo[]'> <input type='file' name='photo[]'>can be automatically recognized. When uploading multiple filesThere is another problem to distinguish 1, 2, 3.. . . n input
//获取商品图片路径和详情图片路径 $str = $this->upload(); $count1 = count($_FILES['files1']['name']);//获取商品图片上传个数 $arr = explode(',',$str); $slider = ''; $detail = ''; foreach ($arr as $k=>$v){ if($k+1<$count1){ $slider .= $v.','; }else{ $detail .= $v.','; } } $slider = rtrim($slider,','); $detail = rtrim($detail,',');Related recommendations:

PHP type prompts to improve code quality and readability. 1) Scalar type tips: Since PHP7.0, basic data types are allowed to be specified in function parameters, such as int, float, etc. 2) Return type prompt: Ensure the consistency of the function return value type. 3) Union type prompt: Since PHP8.0, multiple types are allowed to be specified in function parameters or return values. 4) Nullable type prompt: Allows to include null values and handle functions that may return null values.

In PHP, use the clone keyword to create a copy of the object and customize the cloning behavior through the \_\_clone magic method. 1. Use the clone keyword to make a shallow copy, cloning the object's properties but not the object's properties. 2. The \_\_clone method can deeply copy nested objects to avoid shallow copying problems. 3. Pay attention to avoid circular references and performance problems in cloning, and optimize cloning operations to improve efficiency.

PHP is suitable for web development and content management systems, and Python is suitable for data science, machine learning and automation scripts. 1.PHP performs well in building fast and scalable websites and applications and is commonly used in CMS such as WordPress. 2. Python has performed outstandingly in the fields of data science and machine learning, with rich libraries such as NumPy and TensorFlow.

Key players in HTTP cache headers include Cache-Control, ETag, and Last-Modified. 1.Cache-Control is used to control caching policies. Example: Cache-Control:max-age=3600,public. 2. ETag verifies resource changes through unique identifiers, example: ETag: "686897696a7c876b7e". 3.Last-Modified indicates the resource's last modification time, example: Last-Modified:Wed,21Oct201507:28:00GMT.

In PHP, password_hash and password_verify functions should be used to implement secure password hashing, and MD5 or SHA1 should not be used. 1) password_hash generates a hash containing salt values to enhance security. 2) Password_verify verify password and ensure security by comparing hash values. 3) MD5 and SHA1 are vulnerable and lack salt values, and are not suitable for modern password security.

PHP is a server-side scripting language used for dynamic web development and server-side applications. 1.PHP is an interpreted language that does not require compilation and is suitable for rapid development. 2. PHP code is embedded in HTML, making it easy to develop web pages. 3. PHP processes server-side logic, generates HTML output, and supports user interaction and data processing. 4. PHP can interact with the database, process form submission, and execute server-side tasks.

PHP has shaped the network over the past few decades and will continue to play an important role in web development. 1) PHP originated in 1994 and has become the first choice for developers due to its ease of use and seamless integration with MySQL. 2) Its core functions include generating dynamic content and integrating with the database, allowing the website to be updated in real time and displayed in personalized manner. 3) The wide application and ecosystem of PHP have driven its long-term impact, but it also faces version updates and security challenges. 4) Performance improvements in recent years, such as the release of PHP7, enable it to compete with modern languages. 5) In the future, PHP needs to deal with new challenges such as containerization and microservices, but its flexibility and active community make it adaptable.

The core benefits of PHP include ease of learning, strong web development support, rich libraries and frameworks, high performance and scalability, cross-platform compatibility, and cost-effectiveness. 1) Easy to learn and use, suitable for beginners; 2) Good integration with web servers and supports multiple databases; 3) Have powerful frameworks such as Laravel; 4) High performance can be achieved through optimization; 5) Support multiple operating systems; 6) Open source to reduce development costs.
