この質問はすでにここで答えられるべきであるように思われます、しかし私はそれを見つけることができません、おそらく用語の欠如のためです。うまくいけば、同じ状況にある他の誰かがこれから恩恵を受けることができます。

配列$post_itemがあります。（以下を参照）たとえば、そこからデータを出力します。

$post_item->ID

印刷する順序でどのアイテムを取得する方法はありますか？つまり、アイテムを数えたいのです。

IDが9の商品の場合は0を返します。IDが12の商品の場合は1などを返します。

「キー」（0,1,2 ..）が必要な場合は、配列に変換するだけです。

$arr = array();
foreach($objects as $key=>$val) { $arr[$key] = $val; }

foreach($arr as $key=>$val) {
   if ($val["ID"] == 9) { /* $key is 0,1,2.. */ }
}

おそらく、問題のより良い説明が役立つかもしれません。
