Course Introduction：Create a ZIP file using ZipArchive class: instantiate the object, call the open() method to create the file, addFile() or addFromString() to add content, and finally call close() to save. 2. The entire folder can be added to the ZIP by traversing the directory. 3. Make sure to check the return value of open() and ensure write permissions. 4.PHP uses standard ZIP compression by default. Simple and reliable operation.

Course Introduction：Using the zipfile module in Python can directly create and decompress ZIP files. 1. To create a ZIP file, you need to use the ZipFile class to open the file in write mode, and add the file through the write() method. When packaging the directory, you need to traverse the file recursively and pay attention to the path processing; 2. Unzip the ZIP file to restore the complete directory structure by extractall() method, or you can also selectively extract a single file after viewing the content through namelist(); 3. Other techniques include handling Chinese garbled code, detecting whether the ZIP is corrupt, setting compression levels and password protection (requiring a third-party library). Mastering these key points can meet daily ZIP file operation needs.

Course Introduction：First, confirm that the Zip extension is enabled in the PHP environment, then use the ZipArchive class to open the specified ZIP file and call the extractTo method to extract it to the target directory, and finally close the archive. The sample code shows the compression process and the prompts for success or failure. It is necessary to ensure that the file path is correct, the target directory is writable, and pay attention to preventing security risks such as ZIPslip.

Course Introduction：The core function of PHP files is to handle dynamic web content, combining server-side logic and front-end display. A typical structure includes four steps: introducing configuration files, starting a session, loading an autoloader, and routing and distribution. PHP allows to embed dynamic content in HTML, which is suitable for building template pages, but it is recommended to use the template engine to separate logic from views. In the file introduction method, require is used to ensure that the script terminates in errors, and include is used for optional modules; it is recommended to use the _once version uniformly to prevent duplicate loading. The code organization recommends a separate file for each class, and classifies functions into tool classes or services, and uses namespaces to improve readability and automatic loading efficiency.

Course Introduction：How to use MVC mode in PHP? 1. Set the basic file structure and create three folders: Model, View and Controller; 2. Write model processing logic, such as UserModel class operating database; 3. Create controller to receive requests and coordinate model and view, such as UserController obtaining data; 4. Build view display content, such as user_profile.php mixing HTML and PHP output dynamic data; 5. Unified request processing through the front-end controller index.php, loading the model and controller and executing corresponding methods to achieve application scalability.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
