Article Introduction：JavaScript's setInterval() function is used to automatically execute tasks based on a timer. setInterval() is a native JavaScript function, very similar to jQuery's setTimeout() function. Basic setInterval() example setInterval(function() { // Perform every 5 seconds }, 5000); Tip: If you load the image dynamically and load the variables from the PHP script, you need to add some kind of random number to the script to force all browsers to refresh. Random numbers can be generated using the following code: $(document).ready(

Article Introduction：Core points Use Jump.js library to implement native JavaScript smooth scrolling, simplifying scrolling animation without external dependencies. Modify Jump.js original code to convert it from ES6 to ES5 to ensure wider compatibility with different browsers. Use the requestAnimationFrame method to perform smooth animation updates, optimize performance and provide a smoother user experience. Implement custom JavaScript to intercept the default in-page link behavior and replace sudden jumps with smooth scrolling animations. Integrate the CSS scroll-behavior attribute to support native smooth scrolling in browsers that recognize this feature, and provide Java if the browser does not support it

Article Introduction：JNI allows Java code to interact with local code written in C/C and other languages, and implement it as a shared library by declaring native methods, generating header files, writing and compiling C as a shared library, loading the library and running the program to achieve calls; 2. Data is converted between Java and local types through JNI functions, such as jstring and char*; 3. Local code can callback Java methods, and you need to obtain class references, method IDs and use functions such as CallVoidMethod; 4. When using it, you need to pay attention to naming specifications, exception checking, memory management, thread safety and performance overhead; 5. Applicable to access system resources, reusing native libraries or improving performance, but you should avoid using them when pure Java can solve or emphasize portability; JNI is strong

Article Introduction：LSP is a standardized protocol used to connect editors and language tools to implement functions such as code completion, jump definition and other functions. 1. It enables the editor to support multiple languages once; 2. The logic is unified and convenient for debugging; 3. It can utilize Go native toolchain. To develop Go LSP servers, you need to install Go environment, introduce gopls and lsp packages, create the main function to start the service and listen to communication. MyServer needs to implement interface methods such as initialization, file opening, and processing completion. Basic functions include file opening, code completion, and jump definition. Document URI and location information need to be parsed during requests, and pay attention to caching, error handling and concurrent access issues. Debug recommended output logs, simulate requests using dlv or scripts to ensure that the status is synchronized and correct communication.

Article Introduction：How to implement secure file upload in PHP? 1. Use $_FILES to obtain file information. The form needs to set enctype="multipart/form-data"; 2. Check the file error code to ensure that the upload is normal; 3. Restrict the file type and pass mime_content_type or finfo verification; 4. Control the file size to avoid exceeding the set limit; 5. Handle file name safely, use unique naming or random prefix; 6. Ensure that the upload directory permission is correct and the script cannot be executed; 7. Support multi-file uploading needs to be processed loop-by-cycle.

Article Introduction：Maintain component-level styles to ensure encapsulation and security; 2. Extract duplicate styles into functions or constants to implement DRY and centralized management; 3. Prioritize the use of topic objects rather than inline properties to ensure design consistency; 4. Avoid excessive use of dynamic styles to prevent performance problems, and use memoization if necessary; 5. A unified CSS-in-JS writing method (such as css attributes or styled functions) in the project; 6. Correctly configure server-side rendering to prevent hydration mismatch problems - By following these practices, maintainable, high-performance and scalable CSS-in-JS code can be built.

Article Introduction：Use dynamic import (import()) to implement lazy loading of VueRouter, thereby improving application performance. 1. Change the routing component to the form of ()=>import('@/views/Component.vue'), triggering code segmentation; 2. Construction tools (such as Webpack or Vite) will generate independent JS code blocks for each lazy loading component, which are only loaded when accessing the corresponding route; 3. The code blocks can be named through /webpackChunkName: "name"/ to optimize cache and readability; 4. Be careful to avoid overuse of lazy loading for layout or small shared components, and manually handle the loading state as needed. After correct configuration

Article Introduction：Internationalize your PHP application: Easily implement multilingual support using gettext The global Internet users continue to grow, and many users want to browse your content in their native language. You may think that only an excellent translation is needed to complete the user interface translation of a website, but the bigger challenge lies in writing background code. The traditional software localization process is cumbersome and error-prone, resulting in confusion in code. Some developers even use different versions of code for different regions, which makes codebase management nearly impossible. gettext is an excellent open source tool that simplifies the process and allows you to focus on code writing, while the translator is responsible for handling individually translated files in the target language. Master PHP gettext, expanding the global influence of applications will become
