Parameterized Constructor Example

Here, we will create a class with data members and implement a parameterized constructor to initialize data members.

PHP code to demonstrate the example of parameterized constructor

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.
