right i'm quite new to php but i know the process.
Sometihng like this?

$row =0;
if ($row == 1) {
echo "Row with coloured backgrouond";
}esle{
echo "Row with alternate coloured backgrouond";
}

you will just need a loop/while statment to go through it.
also replace the text with the html for the different row colours.

very easy fist you make your lop then you do % thingy lol:

<?php
$number = NUMBER OF ROWS;
$color1 = First Color;
$color2 = Second Color;
echo<table>";
for($i=1;$i<=$number;$i++) {
if($i % 2) {
echo"<tr bgcolor=$color1>";
} else {
echo"<tr bgcolor=$color2>";
}
echo"
<td>
stuff
</td>
</tr>";
}
echo"</table>";
?>

or assuming class definitions
.dark_row { background-color:#777 }
.light_row { background-color:#AAA }

$row_count = 0;
// while(....whatever....) {
echo '<tr class="' .((++$row_count % 2 == 0) ? 'dark_row' : 'light_row'). '">';
// }

How could I add that to this switching between two classes (alt1 and alt2)?

if (!$id) {

// print the list if there is not editing

$result = mysql_query("SELECT * FROM smallville_episode_guide ORDER BY `id` ASC",$db);

while ($myrow = mysql_fetch_array($result)) {

printf("%s - %s \n", $myrow["id"], $myrow["episode_name"]);

printf(" <a href=\"%s?id=%s\">[edit]</a> \n", $PHP_SELF, $myrow["id"]);

printf(" <a href=\"%s?id=%s&delete=yes\">[delete]</a><br>", $PHP_SELF, $myrow["id"]);

}

}

How about the "ternary" operator?
($color='grey' ? 'white' : 'grey')
is equivalent to:
if ($color == 'black') {
$color = 'white';
} else {
$color = 'grey';
}

$color = 'grey';
}
Shouldn't the "ternary" thingy be:

($color == 'grey') ? $color = 'white' : $color = 'grey';

Anyways I think using the "rest of division" (or whatever it's in english) operator is better.

if (!$id) {

// print the list if there is not editing

$result = mysql_query('SELECT * FROM smallville_episode_guide ORDER BY `id`',$db);

$class = 'alt2';

while ($myrow = mysql_fetch_array($result)) {

$class = ($class == 'alt1') ? 'alt2' : 'alt1';

echo '<div class="'.$class.'">'.$myrow['id'].' - '.$myrow['episode_name']."\n".' <a href="'.$_SERVER['PHP_SELF'].'?id='.$myrow['id'].'">[edit]</a>'."\n".' <a href="'.$_SERVER['PHP_SELF'].'?id='.$myrow['id'].'&delete=yes">[delete]</a></div>';

}

My bad. Actually it was:

$color = ($color='grey' ? 'white' : 'grey');
