Arithmetic Operators:

These are the most basic kind of operators. The PHP Arithmetic operator is used to perform addition(+), subtraction(-), Division(/), Multiplication(*), modulus(%). with variable or value.

Example (Unary Operator):

<?php

$a=-12;

echo $a."<br/>";

$a=-$a;

echo $a."<br/>";

$a++;

echo $a."<br/>";

echo $a--."<br/>";

echo --$a."<br/>";

Output:

-12
12
13
13
11

Example (Binary operator):

<?php

$a=-12+34-45/5*4;

echo $a;

Output:

-14

Example (Binary operator):

<?php

$a=12;

echo $a/6 ."<br/>";

echo $a%5 ."<br/>";
