Explanation / Answer

student.php

<?php

class Student //create class

{

var $sname; // student name

var $sid; // student id

var $sclass; // student class

var $sbranch; //student branch

function Student($name, $id, $class,$branch) //constructor for class Student

{

//varible initialization

$this->sname=$name;

$this->sid=$id;

$this->sclass=$class;

$this->sbranch=$branch;

}

function display() //function defination for display varibles

{

echo "Student Name : ".$this->sname."<br>"; //display intialized student information

echo $this->sname." ID : ".$this->sid."<br>";

echo $this->sname." Class : ".$this->sclass."<br>";

echo $this->sname." Branch : ".$this->sbranch."<br><br>";

}

}

//object creation and display

$obj1=new Student("Ashok1","11111","GF1","CSE");

$obj1->display();

//object creation and display

$obj2=new Student("Ashok2","22222","GF2","ECE");

$obj2->display();

//object creation and display

$obj3=new Student("Ashok3","33333","GF3","MECH");

$obj3->display();

?>

Output :

Student Name : Ashok1
Ashok1 ID : 11111
Ashok1 Class : GF1
Ashok1 Branch : CSE

Student Name : Ashok2
Ashok2 ID : 22222
Ashok2 Class : GF2
Ashok2 Branch : ECE

Student Name : Ashok3
Ashok3 ID : 33333
Ashok3 Class : GF3
Ashok3 Branch : MECH

Math.php :

<?php

class Math //create class

{

var $a; // varible a

var $b; // varible b

var $c; // varible c

function Math($a1, $b1) //constructor for class Math

{

//varible initialization

$this->a=$a1;

$this->b=$b1;

}

function add() //function defination for addition of varibles

{

$this->c=$this->a + $this->b; // add a,b

echo "Addition of ".$this->a.",".$this->b." is ".$this->c."<br>"; //display add result

}

function sub() //function defination for substraction of varibles

{

$this->c=$this->a - $this->b; // sub a,b

echo "substraction of ".$this->a.",".$this->b." is ".$this->c."<br>"; //display sub result

}

function mul() //function defination for substration of varibles

{

$this->c=$this->a * $this->b; // mul a,b

echo "Multiplication of ".$this->a.",".$this->b." is ".$this->c."<br>"; //display mul result

}

function div() //function defination for substration of varibles

{

$this->c=$this->a / $this->b; // div a,b

echo "Division of ".$this->a.",".$this->b." is ".$this->c."<br>"; //display div result

}

}

//object creation and display

$obj1=new Math(10,20);

$obj1->add();

$obj1->sub();

$obj1->mul();

$obj1->div();

?>

Output :

Addition of 10,20 is 30
substraction of 10,20 is -10
Multiplication of 10,20 is 200
Division of 10,20 is 0.5
