PHP program to calculate sum of two numbers using function
In this article, we will discuss the concept of PHP program to calculate sum of two numbers using function
In this post, we are going to learn how to write a program to find addition of two numbers using function in PHP language
Code to sum of two numbers in PHP
Addition of two numbers using function – #1
In this code, we are going to learn how to write a program to calculate addition of two numbers using function in PHP programming language
Program 1
- Start PHP script
- Declare and initiates two integer variable
- Calculate sum of given two numbers
- Display result on the screen
- Exit PHP
In this program, first the user declare variables as parameter in function and then passing the values to variables as argument. Finally when the user call the function, the result is calculated and displayed on the screen
<?php
//function definition
function addTwoNumbers($x, $y)
{
return $x + $y;
}
//Calling the function and print result
echo "Sum of 20 and 30: ".addTwoNumbers(20,30);
echo "<br>";
echo "Sum of 150 and 550: ".addTwoNumbers(150,550);
echo "<br>";
echo "Sum of 100 and -40: ".addTwoNumbers(100,-40);
echo "<br>";
?>
When the above code is executed, it produces the following result
Sum of 20 and 30: 50 Sum of 150 and 550: 700 Sum of 100 and -40: 60
Addition of two numbers using function – #2
In this code, we are going to learn how to write a program to calculate addition of two numbers using function in PHP programming language
Program 2
- Start PHP script
- Declare and initiates two integer variable
- Calculate sum of given two numbers
- Display result on the screen
- Exit PHP
In this program, first the user declare variables as parameter in function and then passing the values to variables as argument. Finally when the user call the function, the result is calculated and displayed on the screen
<?php
//function definition
function addTwoNumbers($x, $y)
{
$sum=$x + $y;
return $sum;
echo $sum;
}
//Calling the function and print result
echo "Sum of 100 and 300: ";
echo addTwoNumbers(100,300);
echo "<br>";
echo "Sum of 100 and 120: ";
echo addTwoNumbers(100,120);
echo "<br>";
echo "Sum of 100 and -200: ";
echo addTwoNumbers(100,-200);
echo "<br>";
?>
When the above code is executed, it produces the following result
Sum of 100 and 300: 400 Sum of 100 and 120: 220 Sum of 100 and -200: -100
