function generatePageTree($datas, $parent = 0, $depth=0){
if($depth > 100) return ''; //Make sure not to have an endless recursion
$tree = '<ul>';
for($i=0, $ni=count($datas); $i < $ni; $i++){
if($datas[$i]->Parent == $parent){
$tree .= '<li>';
$tree .= $datas[$i]->Name;
$tree .= generatePageTree($datas, $datas[$i]->ID, $depth+1);
$tree .= '</li>';
}
}
$tree .= '</ul>';
return $tree;
}
$tree=generatePageTree($categoriesOptions);
echo $tree;
