How to initialize data members without using the constructor in PHP | PHP program

We will define a class Sample class with data members and then initialize private data members using the class method.

<?php
class Student
{

    private $id;
    private $name;
    private $per;

    function Initialize()
    {
        $this->id = 0;
        $this->name = "";
        $this->per = 0.0;
    }

    function Display()
    {
        print ("Student Id  		  : " . $this->id . '<br>');
        print ("Student Name		  : " . $this->name . '<br>');
        print ("Student Percentage : " . $this->per . '<br>');
    }
}

$S = new Student();

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