What is the PHP operator % and how do I use it in real-world examples?

What is the explanation for PHP's
operator % in full
detail?

Including examples would be
nice!

Answer

It's the modulus operator, which gives the
integer remainder of a
division
e.g.

7
            / 2 = 3.5 // 3 remainder 1
7 % 2 = 1 // the
            remainder

Obvious real
world example is working out whether a number is odd or
even

if (($n % 2) == 0) the number is even, else
it's odd... useful when you want to show alternate rows in a table in different
colours
