Code formatting tools in PHP

With the rapid development of the Internet, PHP, as a dynamic language, plays an increasingly important role in network development. In order to improve the readability and maintainability of the code, we usually need to format the PHP code. In this regard, PHP has many excellent code formatting tools. This article will introduce and compare several commonly used PHP code formatting tools.

1. PHP_CodeSniffer

PHP_CodeSniffer is a very easy-to-use PHP code formatting tool.

PHP_CodeSniffer provides two usage methods: command line interface and API interface, which can facilitate integrated development and automated testing.

Using PHP_CodeSniffer can make our code more standardized, easier to read and easier to maintain. However, the check results of PHP_CodeSniffer are not always accurate, and sometimes there are some false positives and false negatives.
