Array trouble - Help needed fast

[Anon]

With PHP 4.0.4 I get an XML document, via Curl, which I use DOM XML to strore the array, $regions. This array contains arrays with these values $id, $parentid, $name and $childs.
$id is unique and a parent or child of a parent.
$parentid is the $id of the parent if any.
$name is not important here.
$childs is set to 1 if any childs.

The top parent elements are countries, which can have regions (childs). Those regions are in them self a parent, and can therefore also have regions.
It's like this: USA is a parent region without a parent, but with California as a child. California is a parent with San Francisco as a child. San Francisco is a parent but with no childs.

Now I need this as a hierarchy of parent/childs, so I can print it or store it in a database or access for instance California and get it's childs.

Have anybody got an idea about how I do that?

I found this from a user on the support docs at www.php.net. It has been very useful when debugging arrays.

function ListArray($var, $title='ListArray')
{
if($title){ $string = ''; }

$string .= '<table border="0" cellpadding="2" cellspacing="1" bgcolor="CCCCCC" style="font-size: 10px;">';
if($title){ $string .= '<tr bgcolor="003346" style="color: whitesmoke;"><td><b>Key</b></td><td><b>Value</b></td></tr>'; }

while(list($key, $val) = each($var))
{
$string .= '<tr bgcolor="whitesmoke">' ;
$string .= "<td valign=\"top\"><b>$key</b></td><td valign=\"top\">";
if(is_array($val)){
$string .= ListArray($val, '');
}else{ $string .= "$val" ; }

$string .= '</td></tr>';
}//While
$string .= "</table>";

if($title){ $string .= ''; }
return $string;
}

$TheArray[1] = 'foo';
$TheArray['bob']] = 'is cool';

ListArray($TheArray);

Hope it helps.
