My Answer:
A class in PHP is a blueprint for creating objects. It defines the properties and methods that an object of that class will have. Classes are used to organize code and create reusable components in object-oriented programming.

Here is an example of a simple class in PHP:

php
class Car {
public $make;
public $model;

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

public function displayInfo() {
echo "This is a {$this->make} {$this->model}.";
}
}

$myCar = new Car("Toyota", "Corolla");
$myCar->displayInfo();


In this example, the `Car` class has two properties (`$make` and `$model`) and two methods (`__construct` and `displayInfo`). We create an object of the `Car` class called `$myCar` and call the `displayInfo` method to display information about the car.
