Build tree from parent_id id table structure - php

Question

I'm trying to build a tree with the exact specifications of..
This Question
Basically I need to create a tree from a parent - id table structure.
I'm using this function to try to achieve the above;
private static function fetch_recursive($src_arr, $currentid = 0, $parentfound = false, $cats = array())
{
foreach($src_arr as $row)
{
if((!$parentfound && $row['category_id'] == $currentid) || $row['parent_id'] == $currentid)
{
$rowdata = array();
foreach($row as $k => $v)
$rowdata[$k] = $v;
$cats[] = $rowdata;
if($row['parent_id'] == $currentid)
$cats = array_merge($cats, CategoryParentController::fetch_recursive($src_arr, $row['category_id'], true));
}
}
return $cats;
}
But I'm getting an error from PHP :
Maximum function nesting level of 100 reached, aborting!
I'm ordering the db results by parent_id and then by id to help out with the issue but it still persists.
As a side note by table contains ~250 records.

Laravel 4 - Eloquent. Infinite children into usable array?
Solution:
<?php
class ItemsHelper {
private $items;
public function __construct($items) {
$this->items = $items;
}
public function htmlList() {
return $this->htmlFromArray($this->itemArray());
}
private function itemArray() {
$result = array();
foreach($this->items as $item) {
if ($item->parent_id == 0) {
$result[$item->name] = $this->itemWithChildren($item);
}
}
return $result;
}
private function childrenOf($item) {
$result = array();
foreach($this->items as $i) {
if ($i->parent_id == $item->id) {
$result[] = $i;
}
}
return $result;
}
private function itemWithChildren($item) {
$result = array();
$children = $this->childrenOf($item);
foreach ($children as $child) {
$result[$child->name] = $this->itemWithChildren($child);
}
return $result;
}
private function htmlFromArray($array) {
$html = '';
foreach($array as $k=>$v) {
$html .= "<ul>";
$html .= "<li>".$k."</li>";
if(count($v) > 0) {
$html .= $this->htmlFromArray($v);
}
$html .= "</ul>";
}
return $html;
}
}
