以下を取得して、各レベルの「--」を含む美しいフォーマットの選択ドロップダウンとしてエコーするにはどうすればよいですか?

このトピックがかなり詳しく取り上げられていることは知っていますが、私にとってはそれほど多くはありません。2 日間の読書の後...そして読書...そして読書...私はついにこのデータをデータベースから取り出すことができました。今、私はそれを最初のカテゴリよりも深く反響させることができないようです.
支援と忍耐に感謝します。
現在、親を取得する方法は次のとおりです。
$レベル = 0;
$categories = $this->mycrate->build_categories();
echo '<select class="input-block-level">'; function RecursiveWrite($categories) { foreach ($categories as $category) { echo '<option value="'.$category->id.'">'.$category->title.'</option>'; RecursiveWrite($category->parent_id); } } RecursiveWrite($categories); echo '</select>';
