Program/Source Code:

The source code to initialize data members without using the constructor is given below. The given program is compiled and executed successfully.

<?php
//PHP program to initialize data members without
//using the constructor.
class Student
{
    //Attributes
    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();
?>

Output:

Student Id : 0
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.
