$S = new Student();

$S->Initialize();
$S->Display();
?>

Student Name :
Student Percentage : 0

Explanation:

In the above program, we created a class Student that contains three data members $id, $name, and $per. Here, we created two methods Initialize() and Display().

The Initialize() method is used to initialize the data members of the class, here we used $this for data members.

The Display() method is used to print the values of data members on the web page.

After that, we created the object "$S" of the Student class and then called both methods.
