PHP Constructor

A constructor is a special method in a class that is automatically called when an object is created. It is used to initialize object properties and perform any setup tasks.

Defining a Constructor

<?php
class Person {
    public $name;

    // Constructor
    public function __construct($name) {
        $this->name = $name;
    }

    public function greet() {
        return "Hello, my name is " . $this->name . ".";
    }
}
?>

Using the Constructor

<?php
$person = new Person("Alice");
echo $person->greet();
?>

Output:

Hello, my name is Alice.

Explanation: This example demonstrates how to define a constructor in a class and how it initializes the object's properties when the object is created.
