In 2025, PHP remains one of the most versatile and widely-used server-side scripting languages. Its ability to handle dynamic content, session tracking, and build robust e-commerce platforms keeps it at the forefront of web development. Understanding how to create a PHP class is essential for building organized and maintainable codebases. Here’s a concise guide on how to create a PHP class in 2025.
A PHP class serves as a blueprint for objects. It encapsulates data and functions that work on data, creating a cohesive module that can be reused across projects. By using classes, developers can achieve better code organization and enhance the readability of their code.
A class definition begins with the keyword class
, followed by the class name. For example, to define a simple class:
1 2 3 4 5 |
<?php class MyClass { // Properties and methods go here } ?> |
Properties are variables that belong to a class. They encapsulate class data and are defined within the class body. In 2025, using typed properties is optimal for clarity and error reduction:
1 2 3 4 5 6 7 8 9 10 |
class MyClass { public string $name; private int $age; // Constructor public function __construct(string $name, int $age) { $this->name = $name; $this->age = $age; } } |
Methods are functions that perform operations on class properties. Define them within the class:
1 2 3 4 5 6 7 8 9 10 11 12 13 |
class MyClass { public string $name; private int $age; public function __construct(string $name, int $age) { $this->name = $name; $this->age = $age; } public function getDetails(): string { return "Name: {$this->name}, Age: {$this->age}"; } } |
To use a class, instantiate it by creating an object:
1 2 |
$person = new MyClass("John Doe", 30); echo $person->getDetails(); // Outputs: Name: John Doe, Age: 30 |
