Assuming that nid = 1 / parentID = 0 is the root.
<?php
$Relationships = array();
foreach($Data as $ID => $Row)
{
$Relationships[$ID] = $Row['nid'];
}
foreach($Data as $ID => &$Row)
{
if (0 != $Row['parentID'])
{
$Data[array_search($Row['parentID'],
$Relationships)]['children'][] = &$Row;
}
}
print_r($Data[0]);
?>
outputs ...
Array

[nid] => 1
[parentID] => 0
[text] => Dashboard
[cls] => x-btn-icon
[icon] => lib/extjs/resources/images/default/icon/Dashboard.png
