Modules

Question

$x=14;
$y=3;
echo$x % $y;
Why the output is 2??

Answer 1

The module operator calculates the remainder of a division.
14 / 3 = 4, with a remainder of 2

Answer 2

Modulo calculates the normal integer division which means your result has no decimals. Your result from integer division consists of two different parts. The First part is your normal divisor, the second the rest, in other words the result of a modulo calculation.

Here are some examples:

0/1 == 0 --> 0%1 == 0
4/2 == 2 --> 0%2 == 0
5/2 == 2 rest 1 --> 5%2 == 1
6/3 == 2 --> 6%3 == 0
7/3 == 2 rest 1 --> 7%3 == 1
8/3 == 2 rest 2 --> 8%3 == 2
