try this code snippet: ($line must be an array)

<table>
<?
$color="#FFFFFF";
foreach ($line as $c)) {  
  if ($color=="#FFFFFF") {  // Alternate background color for readability
	$color="#CCCCCC";
  } else {
	$color="#FFFFFF";
  }
  echo "<tr bgcolor=$color>";
  echo "<td>$c</td>";
  echo "</tr>
}
?>
</table>

what sets the $line and $c var?

you have to set up $line yourself...
example:
$result=mysql_query("SELECT * FROM sometable");
$line=mysql_fetch_array($result);

-or-
$line[]="row 1 text";
$line[]="row 2 text";
...
$line[]="row n text";

then when you hit the foreach($line as $c), the $c variable becomes the value of the current $line and loops until there are no more $lines

Or:

// array for colors.. ("unlimited")
color[0] = "#FFFFFF";
color[1] = "#CCCCCC";
color[2] = "#B5B5FF";
$i = -1; // must be -1, so it will start at 0

echo "<table>";

// switch color
if ($i < count($color)) // if $i is lss than number of colors
  {
    $i++; // add one to $i
  }
else // oops, $i must be the same as number of colors
  {
    $i = -1; // restart $i
  }

echo "<tr bgcolor=\"{$color['$i']}\"><td>test</td></tr>";

echo "</table>";

ps. code is not tested, but in my mind it works perfect.

ps. my way might be easier if you want the users to be able to choose design.. Then you can gather the array from a mysql table, quick, dirty and simple.

It will work almost as a smiley script, only no replacing whatsoever, it's actually easier.

the above code looks very good though, just so it's said.

Sorry for this "flooding" on my behalf, but I forgot to mention:

The code chunk in the middle should be inside your recordset loop, while the others should be outside.

I guess it's obvious, but I just thought it would be worth mentioning.

The first code-chunk above the recordset loop, the second inside, the last (and third) below the recordset loop.

Use the modulus operator

$array = array('data', 'data', 'data', 'data');

foreach ($array as $k => $v) {
 if ($k % 2 == 0) {
  echo 'class1<br>';
 } else {
  echo 'class2<br>';
 }
}
