I have a lot of experience in participating in VSCode offline technology exchange activities, and my main gains include sharing of plug-in development, practical demonstrations and communication with other developers. 1. Sharing of plug-in development: I learned how to use VSCode's plug-in API to improve development efficiency, such as automatic formatting and static analysis plug-ins. 2. Practical demonstration: I learned how to use VSCode for remote development and realized its flexibility and scalability. 3. Communicate with developers: I have obtained skills to optimize VSCode startup speed, such as reducing the number of plug-ins loaded at startup and managing the plug-in loading order. In short, this event has benefited me a lot and I highly recommend those who are interested in VSCode to participate.

Create and manage multiple project workspaces in VSCode through the following steps: 1. Click the "Manage" button in the lower left corner, select "New Workspace", and decide the save location. 2. Give the workspace a meaningful name, such as "WebDev" or "Backend". 3. Switch the project in Explorer. 4. Use the .code-workspace file to configure multiple projects and settings. 5. Pay attention to version control and dependency management to ensure that each project has .gitignore and package.json files. 6. Clean useless files regularly and consider using remote development skills

The reason why the editor crashes after the VSCode plugin is updated is that there is compatibility issues with the plugin with existing versions of VSCode or other plugins. Solutions include: 1. Disable the plug-in to troubleshoot problems one by one; 2. Downgrade the problem plug-in to the previous version; 3. Find alternative plug-ins; 4. Keep VSCode and plug-in updated and conduct sufficient testing; 5. Set up automatic backup function to prevent data loss.

VSCode's support trend for emerging programming languages ??is positive, mainly reflected in syntax highlighting, intelligent code completion, debugging support and version control integration. Despite scaling quality and performance issues, they can be addressed by choosing high-quality scaling, optimizing configurations, and actively participating in community contributions.

Using VSCode in a multi-screen environment can solve layout and display problems by adjusting the window size and position, setting workspaces, adjusting interface scaling, rationally laying tool windows, updating software and extensions, optimizing performance, and saving layout configuration, thereby improving development efficiency.

There are three common methods for PHP comment code: 1. Use // or # to block one line of code, and it is recommended to use //; 2. Use /.../ to wrap code blocks with multiple lines, which cannot be nested but can be crossed; 3. Combination skills comments such as using /if(){}/ to control logic blocks, or to improve efficiency with editor shortcut keys, you should pay attention to closing symbols and avoid nesting when using them.

There are three ways to change the default terminal in VSCode: setting through a graphical interface, editing settings.json file, and temporary switching. First, open the settings interface and search for "terminalintegratedshell" and select the terminal path of the corresponding system; secondly, advanced users can edit settings.json to add "terminal.integrated.shell.windows" or "terminal.integrated.shell.osx" fields and escape the path correctly; finally, you can enter "Terminal:SelectD through the command panel

Comments are crucial in code because they improve the readability and maintenance of the code, especially in projects like PHP that are multi-collaborative and long-term maintenance. Reasons for writing comments include explaining “why do this” to save debugging time and be friendly to newbies and reduce communication costs. The representation of good comments includes explaining the role of functions or classes to explain complex logic intent marking to-dos or potential problems, and writing API interface documentation annotations. Typical manifestations of bad comments include repeated code content comments that are inconsistent with code and using comments to cover up bad code and retaining old information. Suggestions for writing comments include prioritizing comments "why" keeping comments synced with code Use a unified format to avoid emotional statements and consider optimizing code rather than relying on comments when the code is difficult to understand.
