Python Made Powerful: A Beginner's Guide to Effortless Programming

The key to writing PHP comments is to clarify the purpose and specifications. Comments should explain "why" rather than "what was done", avoiding redundancy or too simplicity. 1. Use a unified format, such as docblock (/*/) for class and method descriptions to improve readability and tool compatibility; 2. Emphasize the reasons behind the logic, such as why JS jumps need to be output manually; 3. Add an overview description before complex code, describe the process in steps, and help understand the overall idea; 4. Use TODO and FIXME rationally to mark to-do items and problems to facilitate subsequent tracking and collaboration. Good annotations can reduce communication costs and improve code maintenance efficiency.

The key to writing good comments is to explain "why" rather than just "what was done" to improve the readability of the code. 1. Comments should explain logical reasons, such as considerations behind value selection or processing; 2. Use paragraph annotations for complex logic to summarize the overall idea of functions or algorithms; 3. Regularly maintain comments to ensure consistency with the code, avoid misleading, and delete outdated content if necessary; 4. Synchronously check comments when reviewing the code, and record public logic through documents to reduce the burden of code comments.

There are three common ways to use PHP comments: single-line comments are suitable for briefly explaining code logic, such as // or # for the explanation of the current line; multi-line comments /*...*/ are suitable for detailed description of the functions or classes; document comments DocBlock start with /** to provide prompt information for the IDE. When using it, you should avoid nonsense, keep updating synchronously, and do not use comments to block codes for a long time.

To run the first PHP script, you must first build a server environment, and then write basic code to test and run. 1. Locally install integrated environments such as XAMPP, WAMP or MAMP; 2. Use PHP that comes with Mac or Linux system; 3. Run code through an online PHP editor; 4. Place the PHP file in the server directory such as http://htdocs; 5. Write the included .php file; 6. Visit http://localhost/test/index.php through the browser to view the results; 7. Pay attention to check whether the server is running, whether the path is correct and whether the syntax is wrong; 8. You can try to output time or process forms and deepen your understanding.

The key to writing PHP comments is to explain "why" rather than "what to do", unify the team's annotation style, avoid duplicate code comments, and use TODO and FIXME tags reasonably. 1. Comments should focus on explaining the logical reasons behind the code, such as performance optimization, algorithm selection, etc.; 2. The team needs to unify the annotation specifications, such as //, single-line comments, function classes use docblock format, and include @author, @since and other tags; 3. Avoid meaningless annotations that only retell the content of the code, and should supplement the business meaning; 4. Use TODO and FIXME to mark to do things, and can cooperate with tool tracking to ensure that the annotations and code are updated synchronously and improve project maintenance.

There are three common annotation methods in PHP, namely single-line comments, multi-line comments and document block comments. 1. Single-line comments use // or #, suitable for short descriptions, and can be placed at the end of the code line or a separate line; 2. Multi-line comments start with / and end with /, suitable for detailed descriptions such as function functions or version records; 3. Document block comments start with /**, combined with tags such as @param, @return, etc., can be recognized by IDE and tools for generating code prompts and documents. In addition, it is recommended to write comments for functions and classes, especially public methods; add interpretative comments in complex logic; avoid meaningless comments; and not submit commented debug code. Mastering these annotation methods and usage suggestions will help improve code readability and maintenance efficiency.
