The strong return of match expressions in PHP8 leads to a change in writing style

With the development of modern programming languages, developers are paying more and more attention to writing high-quality, easy-to-maintain code. In this process, the characteristics of language itself also play an extremely important role. Recently, the latest version of the PHP language, PHP8, was released, which introduced a new language feature-match expression.

The match expression is a new conditional statement that can not only replace the original switch statement, but also adopts a more concise and easy-to-read syntax. Many PHP developers welcome the strong return of match expressions, believing that it can significantly improve code readability and maintainability, and lead a change in writing style.

Before PHP8, PHP developers usually used switch statements to implement multiple conditional branches. However, the switch statement itself is not very elegant and requires writing a lot of code to cover all conditional branches. The match expression uses a more concise and easy-to-read writing method, which is more suitable for the requirements of modern programming languages. For example, the following is an example of using a match expression:

$result = match ($input) {
    'a', 'b', 'c' => 'A, B or C',
    'd', 'e', 'f' => 'D, E or F',
    default => 'Something else',
};

As you can see from the above example, the match expression not only writes all the conditional branches together, but also uses arrow operators to simplify code. At the same time, it also supports the default branch, which is used to match all branches that are not explicitly defined. This ensures the code is robust and reduces the risk of errors.

In addition to more concise syntax, match expressions also provide more functions. It can return any type of value, including functions, classes, objects, etc., which greatly improves the readability and maintainability of the code. Moreover, it can also perform type checking and null value checking to ensure the safety and correctness of the code.

Due to the powerful function and elegant syntax of match expressions, more and more PHP developers are beginning to use match expressions instead of switch statements. This can make the code more concise, readable and maintainable, while also improving development efficiency and code quality.

In short, the strong return of match expressions in PHP8 marks a change in writing style. It not only makes the code more elegant and concise, but also provides more functions and features, helping to improve the readability and maintainability of the code. Although it is not yet a savior in the PHP language, it is undoubtedly a powerful tool that has injected new vitality into our programming career.
