PHP program to demonstrate the parameterized constructor

Program/Source Code:

The source code to demonstrate the parameterized constructor is given below. The given program is compiled and executed successfully.

<?php  
    //PHP program to demonstrate the parameterized constructor.
    class Sample
    {  
        private $num1;
        private $num2;
        
        public function Sample($n1, $n2)
        {  
            $this->num1=$n1;
            $this->num2=$n2;
        }  
        public function PrintValues()
        {  
            echo "Num1: ".$this->num1."<br>";  
            echo "Num2: ".$this->num2."<br>";  
        }  
    }  
    $S = new Sample(10,20);  
    $S->PrintValues();
?> 

Output:

Num1: 10
Num2: 20

Explanation:

In the above program, we created a class Sample that contains data members $num1 and $num2. The Sample class contains a parameterized constructor and a method PrintValues().

The parameterized constructor is used to initialized the data members, and PrintValues() method is used to print the values of data members.

$S = new Sample(10,20);

In the above statements, we created the object $S of Sample class then parameterized constructor of Sample class get called automatically and initialized the values of data members.

$S->PrintValues();

In the above statement, we called the PrintValues() method using object $S that will print the values of data members on the webpage.
