How to adapt to the latest PHP code specification changes?

Overview:
Over time, programming language specifications continue to evolve and change. Adapting to the latest PHP coding specification changes is something every PHP developer should focus on. This article will introduce some common PHP code specification changes and provide corresponding code examples to help developers better adapt to these changes.

1. Naming specification changes:
   In the latest PHP code specification, there have been some changes to the naming specification. Variable and function names should now use camelCase instead of underscore delimiters. For example:

   $myVariable
   function myFunction() {}

   Copy after login
2. Changes in file naming convention:
   File names should use dash delimiters instead of underscore delimiters, and be all lowercase. For example, a class file should look like my-class.php, not My_Class.php.

3. Arrangement of block-level elements:
   A blank line should be added after the code block to improve the readability of the code. For example:

   if ($condition) {
   
    // Code here
   
   }

   Copy after login

   Block-level elements should also be separated by a blank line.

4. Constant definition specifications:
   Constants should be named using uppercase letters and underscores and defined before use. For example:

   define('MY_CONSTANT', 123);

   Copy after login
5. Spaces and indentation:
   In the PHP code specification, it is recommended to use four spaces for indentation. This makes the code more readable and ensures consistency between different developers.
6. Code comment specifications:
   In code comments, // should be used for single-line comments, and /* ... */ should be used for multiple lines. Line comments. Comments should clearly explain the purpose and functionality of the code.

7. Naming conventions for classes and methods:
   In the latest PHP code specifications, classes and methods should be named using camel case and use descriptive names to reflect their functions. . For example:

   class MyClass {
    public function myMethod() {}
   }

   Copy after login

Summary:
Adapting to the latest PHP code specification changes is an important task for PHP developers. This article introduces some common PHP code specification changes and provides corresponding code examples to help developers better adapt to these changes. Following the latest coding standards not only improves code readability and maintainability, but also aids code consistency and teamwork. As the PHP community says, "Good coding conventions are not just a rule, but a sign of good development practices." Therefore, we should always pay attention to and adapt to the latest PHP coding convention changes.
