国、州、市、郊外として次の構造を持っています。リストに this のような構造で以下を追加するにはどうすればよいですか。以下の表に従って、DB からデータを json 形式で取得します。それを保存して、次のようなリストに保存したいと思います。

<li>South Africa</li>
<ul>
<li><h3>Gauteng</h3><p>Gauteng Province.</p>
<ul>
    <li>Ekhurhuleni                         
  <ul>                          
    <li class="liid"><a href="#">Actionville</a></li>   
    <li class="liid"><a href="#">Alberton</a></li>
    <li class="liid"><a href="#">Bakerton</a></li>
    <li class="liid"><a href="#">Bedfordview</a></li>
</ul>                   
</li>
</ul>

構造をデータベースに追加し直す必要があるため、キーも保持する必要があります。
これが私のDBテーブルです：

Table Country
CountryID   Country
1           South Africa
2           Egypt


Table Province
ProvinceID    Provincename  CountryID
1             Gauteng       1
2             Eastern Cape  1
3             Free State    1

Table City
CityID        CityName       ProvinceID
1             Ekurhuleni     1


Table Suburb
SuburbID      SuburbName     CityID
1             Actonville     1
2             Germiston      1

            }
        }
    }
}

// do whatever you want with countriesUl
countriesUl.appendTo(document.body);

PHP:

$countries = array();
$q = "SELECT * FROM Country";
$res = mysql_query($q);
while($row=mysql_fetch_assoc($res)){
    $countryId = $row['CountryID'];
    $countries[$countryId] = array("data"=>$row,"provinces"=>array());
    $provinces = &$countries[$countryId]["provinces"];
    $qP = "SELECT * FROM Province P WHERE P.CountryID = $countryId";
    $resP = mysql_query($qP);
    while($rowP = mysql_fetch_assoc($resP)){
        $provinceId = $rowP['ProvinceID'];
        $provinces[$provinceId] = array("data"=>$rowP,'cities'=>array());
        $cities = &$provinces[$provinceId];
        $qC = "SELECT * FROM City C WHERE C.ProvinceID = $provinceId";
        $resC = mysql_query($qC);
        while($rowC = mysql_fetch_assoc($resC)){
            $cityId = $rowC['CityID'];
            $cities[$cityId] = array("data"=>$rowC,'suburbs'=>array());
            // AND SO ON FOR SUBURBS
        }
    }
}

$output="<ul>";
foreach($countries as $countryId=>$countryArray){
    $output.="<li id='$countryId'>";
    $output.="<h1>".$countryArray['data']['countryName']."</h1>";
        $output.="<ul>";
        foreach($countryArray['provinces'] as $provinceId=>$provinceArray){
