How to deal with the latest PHP code specification changes?

Introduction:
As a widely used programming language, the evolution and changes of PHP's code specifications are inevitable. As a developer, understanding and following the latest PHP coding specifications is crucial to writing high-quality, readable and maintainable code. This article will introduce the latest PHP code specification changes and provide some examples to help developers better cope with these changes.

1. Use of spaces:

1. There must be a space before and after operators, commas, and double colons.
2. There must be a space after the left bracket and before the right bracket of a control statement (such as if, for, etc.).

Example:

if ($foo == $bar) {
    // code here
}

for ($i = 0; $i < 10; $i++) {
    // code here
}

2. Naming convention:

1. Use lowercase letters and underline (snake_case) naming method for variable and function names.
2. Class names use camel case naming starting with an uppercase letter.

Example:

$my_variable = 10;
function my_function() {
    // code here
}

class MyClass {
    // code here
}

3. Functions and methods:

1. There are no spaces after the parentheses of functions and methods.
2. If the function or method has no parameters, parentheses must still be retained.

Example:

function my_function() {
    // code here
}

function my_function_with_parameters($param1, $param2) {
    // code here
}

4. Code indentation:

1. Use four spaces as the indentation standard.
2. Do not use tabs for indentation.

Example:

if ($foo == $bar) {
    for ($i = 0; $i < 10; $i++) {
        // code here
    }
}

5. Comments:

1. Use double slashes (//) for single-line comments, and multi-line comments using slashes and Surrounded by asterisks (/ ... /).
2. Leave two spaces before the comment and maintain appropriate indentation with the code.

Example:

// This is a single-line comment

/*
 * This is a multi-line
 * comment
 */

Conclusion:
With the advancement of the times and the continuous evolution of PHP code specifications, developers need to understand and respond to the latest PHP code specification changes. This article introduces the latest PHP code specification changes and provides some sample code to help developers better follow these specifications. By following the latest PHP code specifications, we can write higher-quality, easier-to-read and maintain code, improving our development efficiency and code quality.
