Also it's always nice to write a function for these things

PHP Code:

function is_even($num)
{
        if($number % 2 == 0)
        {
                return true;
        }
        else
        {
                return false;
        }
} 


Then to check if it's even use this:

PHP Code:

$number = 2;
if(is_even($number))
{
       echo 'it\'s even!';
}
else
{
        echo 'it\'s not even!';
}
