Detailed explanation of how to modify the code format of PHP

With the development of the PHP language, the scale of code projects is getting larger and larger. If the PHP code format is not standardized, it will bring a lot of unnecessary trouble to developers. In this article, we will introduce how to modify the code format of PHP to make the code more standardized and easier to read, while reducing problems caused by non-standard code.

1. Use automatic formatting tools

There are many automatic formatting tools on the market, such as PhpStorm, PHP Beautifier or PHP_CodeSniffer. This type of tool can automatically adjust the code format through certain rules, such as indentation, code wrapping, etc., to make the code more readable and beautiful.

Taking PhpStorm as an example, we can automatically format the php file by pressing the shortcut key Ctrl Alt L, and then PhpStorm will automatically arrange the code and adjust the code to a standardized format. In addition, it can also customize code specifications and customize the style specifications of its own code according to the actual needs of the project.

2. Code specification suggestions

On the other hand, we can also adjust the code format from the following aspects:

2.1 Code indentation

Indentation is one of the most basic elements in code format. A good indentation format can make the code structure clearer and easier to read. Normally, an indentation uses four spaces or a tab.

2.2 Line length

The length of each line in the code should also be controlled within a reasonable range, usually about 80 characters. This ensures that the code is more readable and easier for other developers to maintain.

2. 3 Comments

Comments are one of the important factors for code readability. They allow developers to quickly understand the functions and logic of the code. It is recommended to add them to the code. Necessary comments to explain the function of the code and the author. The comment format generally starts and ends with a slash and an asterisk.

2.4 Variable naming rules

Good coding habits should start with the standardization of variable names. The naming of variables should be clear and concise, and some ambiguous abbreviations should not be used in order to shorten the coding length. You can use camel case naming or underline naming to standardize your variable naming.

To sum up, by using automatic formatting tools, standardized indentation, comments, variable naming, etc., we can easily implement standardized modifications to PHP code. Only by maintaining code writing standards can we ensure the readability and maintainability of the code during the long-term operation of the project, and bring a better experience to developers.
