rreee
このようなオブジェクト配列を取得しました。配列内の各オブジェクトのキーは保持される必要がありますが、post_parent の値は同じです。関数を記述するにはどうすればよいですか? ? ?

マスター、$ar がどこから来たのかわかりません。説明してください。
そして、この $o->post_partent は、この多次元配列内のすべての post_parent の値ですか?
また、あなたの書き方には非常に混乱しています。 。また短縮したんですか？

これは私が書いた方法ですが、あなたに比べれば本当に弱いです！ ！ホームページのスライドショーの効果を実現するために、それが行われていることがわかります。

$ar は私が出力した配列オブジェクトです

元の投稿者のメソッドは明らかに考えすぎで、複雑すぎるようです

うろ覚えです
