Article 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.

Article 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.

Article Introduction：Writing PHP block comments should be standardized and practical, and is suitable for instructions on large segments of structured code such as functions, classes, and file headers. 1. Usage scenarios include function description, class design intention, complex logical process, copyright information, etc.; 2. The standard format adopts /.../ package, follows the PSR-5 standard, summarizes the first line in one sentence, explains in detail after emptying the line, and uses @param, @return, @throws and other tags to explain the parameters and return values; 3. Practical suggestions include keeping the content concise, aligning and beautiful, avoiding redundancy, and regularly maintaining the consistency of annotations; 4. Common misunderstandings such as inconsistent annotations and code, ignoring the use of tags, and verbose content, you should use the IDE to automatically generate templates to improve efficiency. Standardized block annotations help improve code readability and teamwork
