PHP: Checking if number is even or uneven

Anyone know any code to check if a number is even or uneven?

I need it to make one cell out of two a different colour, in a table.

Never mind; I found a solution:

Code:

$i=0;
while( blabla )
{
$colour = ($i++ & 1) ? 'colour1' : 'colour2';
}

You could use the % operator: This gives you the remainder when you divide two numbers. So any even number (by defninition) will have a remainder of zero when divided by 2. And that's how you can do it.

But you do have another solution that works in an interative context.
