What is Constructor? Explain with Example

What is Constructor:

• is a member function of a class which initializes objects of a class
• If you create a __construct() function, PHP will automatically call this function when you create an object from a class.
• Class name and method name are same that called as a constructor

Example: 

<?php

class Employee

{

var $empcode;

var $empname;

function Employee()

//not passed as a parameter

{

$this->empcode = 100;

$this->empname='avadh tutor';

}

function display()

{

echo "<h1><br>";

echo "<br>Emp Code = " . $this->empcode;

echo "<br>Emp Name = " . $this->empname;

echo "</h1>";

}

};

$instance = new Employee(); // Constructor automatically call

$instance -> display();

?>
