Changing bg colors

[Anon]

I am making a shoutbox and I want to know how to have the bgcolor of the background of the <td>'s go back and forth...like how this forum does it. How do I do it?

[lucidfx]

well the premise is to have a certain action happen every other time. I use Modulus but here is an easy to follow / understand example

$count=0;

while (whatever)//sql query ? who knows
{
if (count==0)
{
$bg=color Y;
}
else if (count==1)
{
$bg=color X;
$count=0;
}
$count++;

print table info with bgcolor=$bg;

}//end while

so what it does is initalize to 0 then go through its 0 so make bg Y then inc count then go through count=1 so bg =X count =0 then does it all over

hope this helps, give you the general idea.
something like that, should get you the general idea.

so those commands will alternate..

A "simpler" way:

$bgcolor="black";

while(something)
{
echo $bgcolor;

if ($bgcolor=="black")
{
$bgcolor="white";
}
else
{
$bgcolor="black";
};

};

I've seen an even cooler solution that involved a =% or something, but I can't remember it, so, the way I do it:

echo ($color = !$color) ? '#aabbcc': '#ddeeff';

This will assign $color to not itself each iteration and will flip-flop between the two colors.
