PHP Arithmetic Operators Explained with Examples – Complete Beginner Guide

 

Introduction

PHP Arithmetic Operators are used to perform basic mathematical calculations in PHP programming. These operators allow developers to add, subtract, multiply, divide, and find remainders easily. They are the foundation of all numerical operations in PHP.

What are PHP Arithmetic Operators?

• Addition (+)
• Subtraction (-)
• Multiplication (*)
• Division (/)
• Modulus (%)
• Exponentiation (**)

Arithmetic Operators php Example :-

<?php

$no1 = 20;

$no2 =5;

//ope

$add =$no1 + $no2;

$sub= $no1 - $no2;

$multi= $no1 *$no2;

$divi =$no1 / $no2;

$remainder = $no1 % $no2;

//out

echo "Addition =".$add;

echo"<br>subtraction =".$sub;

echo "<br> multiplication =".$multi;

echo "<br> division=".$divi;

echo"<br> remainder = ".$remainder;

?>

Arithmetic Operators phpOutput :-

Addition =25
subtraction =15
multiplication =100
division=4
remainder = 0
