Test if number is odd or even in php

Solution for : What is the simplest most basic way to find out if a number/variable is odd or even in PHP? Is it something to do with mod?

You were right in thinking mod was a good place to start. Here is an expression which will return true if $number is even, false if odd:

?

1	$number % 2 == 0

Example:

?

1 2 3 4

$number = 20; if ($number % 2 == 0) {   print "I am even"; }

Output:

I am even
