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.
