nested repeat region/data display

[jarow]

I have the following nested repeat region:

$base_phylum = '';
$base_class = '';
$base_order = '';
$base_family = '';

mysql_query......
while($row = mysql_fetch_array($query))
{
// assumes $row['class'] / $row['order'] etc
if($base_phylum !== $row['phylum'])
{
echo $row['phylum'].' ';
$base_class = $row['phylum'];
}
if($base_class !== $row['class'])
{
echo $row['class'].' ';
$base_class = $row['class'];
}
if($base_order !== $row['order'])
{
echo $row['order'].' ';
$base_order = $row['order'];
}
if($base_family !== $row['family'])
{
echo $row['family'].' ';
$base_family = $row['family'];
}
echo $row['species'].'<br />';
}

NOW, I am now trying to design the data display and want to do the following:

1. indent each category (without the periods) like:

phylum
.........class
...............order
......................family
.............................species

2.

If, for example, there is no family or order for a particular speciesI would want species to appear indented right under class as follows:

phylum
.........class
...............species

any ideas how I may do this?

Thanks again for your ideas

Jim

well try this , I haven't testet it, but i think it will work

$base_phylum = '';
$base_class = '';
$base_order = '';
$base_family = '';
$dot = "";

mysql_query......
while($row = mysql_fetch_array($query))
{
// assumes $row['class'] / $row['order'] etc
if($base_phylum !== $row['phylum'])
{
echo $dot.$row['phylum'].'<br> ';
$base_class = $row['phylum'];
for($i=0;$i<strlen($base_class);$i++) {
  $dot .= ".";
}
}
if($base_class !== $row['class'])
{
echo $dot.$row['class'].'<br> ';
$base_class = $row['class'];
for($i=0;$i<strlen($base_class);$i++) {
  $dot .= ".";
}
}
if($base_order !== $row['order'])
{
echo $dot.$row['order'].'<br> ';
$base_order = $row['order'];
for($i=0;$i<strlen($base_order);$i++) {
  $dot .= ".";
}
}
if($base_family !== $row['family'])
{
echo $dot.$row['family'].'<br> ';
$base_family = $row['family'];
for($i=0;$i<strlen($base_family);$i++) {
  $dot .= ".";
}
}
echo $row['species'].'<br>';
}
