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.
