私はこのような配列+オブジェクトを持っています。

Array
(
    [0] => stdClass Object
        (
            [tid] => 1
            [parent_id] => 0

この配列+json文字列のオブジェクト

[{"tid":"1","parent_id":"0","language":"th","t_type":"category","t_name":"cat1","t_description":null,"t_uri":"cat1","t_uri_encoded":"cat1","t_uris":null,"meta_title":null,"meta_description":null,"meta_keywords":null,"childs":[{"tid":"3","parent_id":"1","language":"th","t_type":"category","t_name":"cat1.1","t_description":null,"t_uri":"cat1.1","t_uri_encoded":"cat1.1","t_uris":null,"meta_title":null,"meta_description":null,"meta_keywords":null,"childs":[{"tid":"5","parent_id":"3","language":"th","t_type":"category","t_name":"cat1.1.1","t_description":null,"t_uri":"cat1.1.1","t_uri_encoded":"cat1.1.1","t_uris":null,"meta_title":null,"meta_description":null,"meta_keywords":null}]},{"tid":"4","parent_id":"1","language":"th","t_type":"category","t_name":"cat1.2","t_description":null,"t_uri":"cat1.2","t_uri_encoded":"cat1.2","t_uris":null,"meta_title":null,"meta_description":null,"meta_keywords":null}]},{"tid":"2","parent_id":"0","language":"th","t_type":"category","t_name":"cat2","t_description":null,"t_uri":"cat2","t_uri_encoded":"cat2","t_uris":null,"meta_title":null,"meta_description":null,"meta_keywords":null}]

このようにネストされた ul li を作成する方法。

<ul>
  <li>cat1
    <ul>
        <li>cat1.1
            <ul>
                <li>cat1.1.1</li>
            </ul>
        </li>
        <li>cat1.2</li>
    </ul>
  </li>
  <li>cat2</li>
</ul>

これは私が試したことです

echo list_nested_cat( $list_item );
function list_nested_cat( $list_item, $start = 0) {
    echo '<ul style="margin-left: 1em;">';
    foreach ( $list_item as $item ) {
        if ( isset( $item->childs ) && is_array( $item->childs ) ) {
            echo '<li>'.$item->t_name.'</li>';
            list_nested_cat($item->childs);
        } else {
            echo '<li>'.$item->t_name.'</li>';
        }

    }
    echo '</ul>';
}

しかし、この関数は間違った html ネストされた ul li 形式をエコーし​​ます。

ps。arnaud576875 のコードから配列オブジェクトを作成します

これで始められるはずです：

再帰関数を使用します。それは自分自身を呼び出します。

更新しました

JSON オブジェクトでテストし、いくつかのエラーを修正しました

<?php    

echo make_ulli($object); 

function make_ulli($array){
    if(!is_array($array)) return '';

    $output = '<ul>';
    foreach($array as $item){  

        $output .= '<li>' . $item->t_name;      

        if(property_exists($item, 'childs'))
            $output .= make_ulli($item->childs);

        $output .= '</li>';

    }   
    $output .= '</ul>';

    return $output;
}
