Naming Convention PHP

In PHP programming, the most commonly used naming convention is the “snake_case” style for variables, functions, and class methods. This convention involves using all lowercase letters and separating words with underscores. For example:

  • Variables: $person_age
  • Functions: calculate_total()
  • Class methods: get_user_name()

Snake case is widely adopted in the PHP community and is recommended by the official PHP coding standards (PSR-12). It enhances readability, makes code more consistent, and aligns with the conventions used in the PHP core and popular PHP frameworks.

Naming Convention PHP for Variables

In PHP, variables are commonly named using the snake case convention. This involves using all lowercase letters and separating words with underscores. For example: $person_age, $total_students. Using snake case enhances readability and ensures consistency within the PHP community. Here is some example:

$person_age
$full_name
$num_of_students
$is_logged_in

Naming Convention PHP for Function Name

In PHP, functions are commonly named using camel case convention, where the first letter of each word (except the first) is capitalized. For example: getUserDetails(), calculateTotalAmount(). This convention enhances code readability and maintains consistency within the PHP community. Remember to follow project or framework-specific guidelines for naming functions.

getUserDetails();
calculateTotalAmount();
validateEmailAddress();

Naming Convention PHP for Class Name

In PHP, class names follow Pascal case convention where each word’s first letter is capitalized. For instance: class User, class DatabaseConnection. This convention ensures readability and consistency within PHP community. Adhering to project or framework guidelines is essential for maintaining codebase uniformity.

class User
class DatabaseConnection
class ShoppingCart

Naming Convention PHP for Method Names (inside a class)

In PHP, method names (inside a class) follow camel case convention where the first letter is lowercase and subsequent words start with an uppercase letter. For example: getUserDetails(), calculateTotalAmount(). This convention enhances code readability and maintains consistency within the PHP community. Adhere to project or framework guidelines for naming methods in order to ensure a unified codebase.

getUser()
calculateTotal()
addItemToCart()
validateInput()

Naming Convention PHP for Constant Name

In PHP, constant names follow SCREAMING_SNAKE_CASE convention, using all uppercase letters and underscores as separators. For example: MAX_LOGIN_ATTEMPTS, DEFAULT_TIMEZONE. This convention ensures clarity and distinguishes constants from variables. Consistency with project or framework guidelines is vital for a unified codebase.

define('MAX_LOGIN_ATTEMPTS', 5);
define('DEFAULT_TIMEZONE', 'UTC');
define('API_BASE_URL', 'https://api.example.com');

While using the snake case convention is considered good practice in PHP, it’s important to follow any specific naming conventions or guidelines provided by the framework or project you are working on. Consistency within your codebase is crucial for maintainability and collaboration.
