PHP fmod()

The fmod() function returns the remainder (modulo) of x/y. The name stands for “floating modulo” and the function calculates the modulo of any division which may contain a float as both dividend and divisor.

Syntax

fmod(x,y);

The function takes two required parameters - the x specifies the dividend and the y specifies the divisor.

Example

This example returns the remainder of x and y.

<?php
   $x = 27;
   $y = 5;
   $remainder = fmod($x,$y);
   echo $remainder;
?>
