CONSTRUCTOR

PHP 5 allows developers to declare constructor methods for classes.
Constructor is suitable for any initialization that the object may need before it is used.
We can design constructor using "__construct" or same name as class name.
Parent constructors are not called implicitly if the child class defines a constructor. In order to run a parent constructor, a call to parent::__construct().

Example 1

<?php
	class Example
	{
		public function __construct()
		{
			echo "Hello w3cschoool";
		}
	}
	$obj = new Example();
	$obj = new Example();
?>

Output:

Example 2

<?php
	class demo
	{
		public function demo()
		{
			echo "constructor1...";
		}
	}
	
	class demo1 extends demo
	{
		public function __construct()
		{
			echo parent::demo();
			echo "constructor2...";
		}
	}
	$obj= new demo1();
?>
