What is the difference between division (/) and modulus (%) in PHP?
The division operator (/) gives the result of dividing one number by another. The modulus operator (%) gives only the remainder of that division.
<?php
$a = 10;
$b = 3;
echo $a / $b . "<br>"; // division
echo $a % $b . "<br>"; // modulus (remainder)
echo intdiv($a, $b); // whole number part only
?>Output:

Modulus is often used to check even or odd numbers. If $number % 2 is 0, the number is even.
Note:
In PHP 8, dividing or using modulus with zero throws a DivisionByZeroError. Check the divisor before the calculation.
