How to alternate between bg colors?

[Anon]

How can I write a script that will alternate between table cell bakground colors when displaying results, like the effect used on UBB home pages and the like, eg forums.fanhost.com ?

Depends on how you get your data, but if it's comming from a database, and your are looping through the results you can just do this:

$bgcolor = "white";
$i = 1;

//start loop
if ($i%2) {
$bgcolor = "grey";
}
else {
$bgcolor = "white";
}
$i++

//output your row using $bgcolor as the background color

Another method of alternating row colours in a loop is like so:

  $col1 = "#CCCCCC";
  $col2 = "#DDDDDD";
  $col = $col1;

  echo "<table>\n";

  while (<your conditions here>) {

    echo "<tr bgcolour=\"$col\">\n";
    echo "<td>Cell Data</td>\n";
    echo "</tr>\n";

    $col == $col1 ? $col = $col2 : $col = $col1;

  }

  echo "</table>\n";

$bgcolor = "#ffffff";

while(list($k,4v) = @each($some_array)) {
$bgcolor = ($bgcolor == "#ffffff" ?
"#000000" :
"#ffffff");
print the table here with $bgcolor ....

}
