The __construct Method

The __construct method is a special class method that is automatically called when creating a new object. It is used to initialize object properties or perform other initial settings. Unlike regular methods, the constructor does not need to be called explicitly.

Syntax

class ClassName {
	public function __construct([parameters]) {
		// initialization code
	}
}

Example

Let's create a simple class with a constructor that sets the $name property:

<?php
class User {
	public $name;
	
	public function __construct($name) {
		$this->name = $name;
	}
}

$user = new User('John');
echo $user->name;
?>

Code execution result:

'John'

Example

The constructor can accept multiple parameters and perform complex initialization:

<?php
class Product {
	public $id;
	public $price;
	
	public function __construct($id, $price) {
		$this->id = $id;
		$this->price = $price * 1.2; // Adding 20% VAT
	}
}

$product = new Product(101, 100);
echo $product->price;
?>

Code execution result:

120
