Default or No-Argument Constructor Using __construct()

Here, we will create a class that contains the default or no-argument constructor using __construct(), as we know that constructor of a class called automatically when the object of a class gets created.

PHP code to demonstrate the example of default or no-argument constructor using __construct()

The source code to implement the default or no-argument constructor using __construct() is given below. The given program is compiled and executed successfully.

<?php  
    //PHP program to implement the default or no argument 
    //constructor using __contruct().
    class Sample
    {  
        public function __construct()
        {  
            echo "Default constructor called<br>";  
        }  
        public function  Method1()
        {  
            echo "Method1 called<br>";  
        }  
    }  
    $S = new Sample();  
    $S->Method1();
?>  

Output

Default constructor called
Method1 called

Explanation

In the above program, we created a class Sample that contains a default constructor and a method Method1(), here we implemented constructor using __construct().

$S = new Sample();  

In the above statements, we created the object $S of Sample class then the constructor of Sample class gets called automatically and print "Default constructor called" message on the webpage.

$S->Method1();

In the above statement, we called the Method1() using object $S that will print "Method1 called" message on the webpage.
