In this tutorial, you shall learn about Arithmetic Modulus Operator in PHP, its syntax, and how to use this operator in PHP programs, with examples.
PHP Modulus
PHP Arithmetic Modulus Operator takes two numbers as operands and returns the remainder of the integer division (first operand / second operand).
Symbol
%
symbol is used for Modulus Operator.
Syntax
The syntax for modulus operator is
operand_1 % operand_2
The operands could be of any numeric datatype: integer or float.
Examples
1. Modulus of Integers
In the following example, we take integer values in $x
and $y
, and find the remainder of the division $x / $y
.
PHP Program
<?php
$x = 9;
$y = 4;
$output = $x % $y;
echo "x = $x" . "<br>";
echo "y = $y" . "<br>";
echo "x % y = $output";
?>
Output
2. Modulus of Float Values
In the following example, we take floating point values in $x
and $y
, and find the result of division $x / $y
.
PHP Program
<?php
$x = 9.5;
$y = 4.1;
$output = $x % $y;
echo "x = $x" . "<br>";
echo "y = $y" . "<br>";
echo "x % y = $output";
?>
Output
Conclusion
In this PHP Tutorial, we learned how to use Arithmetic Modulus Operator to find the remainder in the division operation.
