What is the impact of writing php without comments?

php is a very practical programming language that plays a very important role in website development. Whether you are developing dynamic web pages or writing website backends, PHP is an essential tool. However, when writing code, you must pay attention to writing comments, otherwise it will bring great difficulties to later development and maintenance.

In daily development work, I often hear many PHP programmers complaining that they have encountered a certain problem and need to find out the cause of the problem, but there are no comments in the entire program, and they can only work hard line by line. Read the code carefully and get closer to the problem. This situation is indeed very troublesome.

If you are a PHP programmer, it is recommended that you pay attention to writing comments while writing code. First, writing comments can give you a clearer understanding of the logic and structure of your code. For yourself, you can review your code better and clearly know what each part of the code does; for other developers, you can understand your code faster and start developing faster.

Secondly, writing comments can also improve the maintainability of the code. Comments can describe the implementation and purpose of the code, making it easier for others to understand the intent of the code when reading the code. This is very helpful for later maintenance and expansion. If developers neglect the writing of comments, they are likely to encounter some unsolvable problems during the maintenance process, resulting in a waste of time and energy, or even a situation where the code cannot be repaired.

Finally, debugging code also requires the support of comments. Sometimes, during the entire program running process, there may be a problem with a certain function or part of the code. Without comments, it would be impossible to fill in the debugging points. With comments, you can quickly locate the key parts of the code, analyze the cause of the problem, and solve the problem quickly.

Although writing comments is not necessary in the development of some small projects or small functions, the importance of comments becomes particularly obvious in the development of large projects and complex functions. Reasonable comments can improve the readability and maintainability of the code and reduce the risk of problems and errors.

In general, don’t forget to write comments when writing code. Comments allow you to better understand your code, improve the readability and maintainability of the code, and avoid difficulties in later development and maintenance. I believe that as long as we pay attention to the writing of comments, we will be able to write higher quality code and perform better.
