[sandvall02]

ex. 1 record grey

With some function. Which one do I use.

There are a couple of approaches to this, but this is how I do it -

<?
// run query and check number of rows returned

for($i = 0; $i < $num_results; $i++) {

$row = mysql_fetch_array($result);
$value1 = $row[0];
$value2 = $row[1];
$value3 = $row[2];

if ($i % 2 == 1) {	//if odd index print one colour
	$color = 'white';
	}
else {			//else print other colour
	$color = 'grey';
	}
echo "<tr bgcolor=\"$color\"><td>$value1</td><td>$value2</td><td>$value3</td></tr>\n";
}

?>

Hope this helps 😉
