Arithmetic Operators in php

Using Arithmetic Operators
To perform mathematical operations on variables, use the standard arithmetic
operators, as illustrated in the following example:

<?php

// define variables

$num1 = 101;

$num2 = 5;

// add

$sum = $num1 + $num2;

// subtract

$diff = $num1 - $num2;

// multiply

$product = $num1 * $num2;
// divide

$quotient = $num1 / $num2;

// modulus

$remainder = $num1 % $num2;

?>

To perform an arithmetic operation simultaneously with an assignment, use the

two operators together. The following two code snippets are equivalent:

<?php

$a = $a + 10;

?>

<?php

$a += 10;

?>

Operator	What It Does
=	Assignment
+	Addition
-	Subtraction
*	Multiplication
/	Division; returns quotient
%	Division; returns modulus
&&	Logical AND
\|\|	Logical OR
xor	Logical XOR
!	Logical NOT
++	Addition by 1
