alternating for function

[rulian]

okay, how would I go about doing this, I'm running a for loop to display a single table row of data, but I want the background on the rows to change color, so that the user can distinguish the rows,
for ex.
row one-bg = blue
row two-bg = yellow
row three-bg=blue
row four-bg = yello
and so fourth?
all within the same loop?
like is there a way to check if the numer is even or odd?

use style sheets and do it this way:

$color = 1;
while(get data) {
echo "<tr class='data$color'><td>data</td></tr>";
$color = ($color==1) ? 2 : 1;
}

or if you are lazy do it this way

$color = "yellow";
while(get data) {
echo "<tr><td bgcolor='$color'>data</td></tr>";
$color = ($color=="yellow") ? "blue" : "yellow";
}

actually, i took an even lazier way and just made a swich
while (data)
swich($color){
case "blue":
$color='yellow';
breka;
case "yellow":
$color='blue';
break;
}

echo "
<td bgcolor=$color>data";

thanks anyway
