PHP Arithmetic Operators

The PHP arithmetic operators are used with numeric values to perform common arithmetical operations, such as addition, subtraction, multiplication etc.

Operator Name Example Result
+ Addition $x + $y Sum of $x and $y
- Subtraction $x - $y Difference of $x and $y
* Multiplication $x * $y Product of $x and $y
/ Division $x / $y Quotient of $x and $y
% Modulus $x % $y Remainder of $x divided by $y
** Exponentiation $x ** $y Result of raising $x to the $y'th power

Addition

Syntax: 


<!DOCTYPE html>
<html>
<body>

<?php
$x = 10;  
$y = 6;

echo $x + $y;
?>  

</body>
</html>

Output: 


16

Subtraction

Syntax: 


<!DOCTYPE html>
<html>
<body>

<?php
$x = 10;  
$y = 6;

echo $x - $y;
?>  

</body>
</html>

Output: 



4

Multiplication

Syntax: 


<!DOCTYPE html>
<html>
<body>

<?php
$x = 10;  
$y = 6;

echo $x * $y;
?>  

</body>
</html>

Output: 


60

Division

Syntax: 


<!DOCTYPE html>
<html>
<body>

<?php
$x = 10;  
$y = 6;

echo $x / $y;
?>  

</body>
</html>

Output: 


1.6666666666667

Modulus

Syntax: 



<!DOCTYPE html>
<html>
<body>

<?php
$x = 10;  
$y = 6;

echo $x % $y;
?>  

</body>
</html>

Output: 



4

Exponentiation

Syntax: 


<!DOCTYPE html>
<html>
<body>

<?php
$x = 10;  
$y = 3;

echo $x ** $y;
?>  

</body>
</html>

Output: 


1000
