私はこのような配列を持っています
Array
(
[0] => Array
(
[name] => Region
[id] => 3
[parent_id] => 2
[children] => Array
(
[0] => Array
(
[name] => Asia
[id] => 4
[parent_id] => 3
[children] => Array
(
[0] => Array
(
[name] => Central Asia
[id] => 6621
[parent_id] => 4
[children] => Array
(
[0] => Array
(
[name] => Afghanistan
[id] => 5
[parent_id] => 6621
[children] => Array
(
[0] => Array
(
[name] => Balkh
[id] => 6
[parent_id] => 5
[children] => Array
(
[0] => Array
(
[name] => Mazar-e-Sharif
[id] => 7
[parent_id] => 6
)
)
)
[1] => Array
(
[name] => Kabol
[id] => 10
[parent_id] => 5
)
[2] => Array
(
[name] => Qandahar
[id] => 12
[parent_id] => 5
)
)
)
)
)
[1] => Array
(
[name] => Middle East
[id] => 6625
[parent_id] => 4
[children] => Array
(
[0] => Array
(
[name] => Armenia
[id] => 14
[parent_id] => 6625
)
)
)
)
)
)
)
)
ul-li今、私はこの配列をツリー形式に変換したい
しかし、それは私に奇妙な出力を与えています
たとえば、Region 私はこのようにしたい
<li id=3 parent_id=2 > Region </li>
ここで使用idしたいのですがparent_id、属性としてphp関数は
function olLiTree($tree)
{
echo '<ul>';
foreach($tree as $key => $item) {
if (is_array($item)) {
echo '<li>', $key;
olLiTree($item);
echo '</li>';
} else {
echo '<li>', $item, '</li>';
}
}
echo '</ul>';
}
領域の出力は、上記の関数から次のようになります
<ul>
<li>0
<ul>
<li>Region</li>
<li>3</li>
<li>2</li>
<li>children
<ul>
