PHP Classes and Objects

In object-oriented programming (OOP) in PHP, classes and objects are the building blocks. A class defines a blueprint, and an object is an instance of that class.

Creating a Class

To create a class in PHP, use the class keyword:

      
        <?php
          class Car {
            public $color;
            public $model;

            public function __construct($color, $model) {
              $this->color = $color;
              $this->model = $model;
            }

            public function getDetails() {
              return "This car is a $this->color $this->model.";
            }
          }

          $myCar = new Car("Red", "Toyota");
          echo $myCar->getDetails(); // Outputs: This car is a Red Toyota.
        ?>
