そして、71、73などのIDを持っているので、IDが73などの配列からレコードを取得したいと思います。

どうすれば入手できますか。

これはそれほど難しいことではないことはわかっていますが、1 行で取得することはできません。配列の foreach ループを実行してレコードを取得し、ID と一致させることはできますが、配列に何千ものレコードがある場合、それは間違った方法になります。そのため、レコードを取得する直接的な方法を尋ねています。

これに対する解決策は（ループを使用する場合を除いて）1行だけでは見つかりません。"array_search()" や "in_array()" のような関数は 1 次元配列に対してのみ機能し、2D 配列のように見えるためです。

最初にこのオブジェクトを次のようにトラバースします....

$result = array();
foreach ($your_array as $key => $value) {
    $result[] = $value->id;
}
print_r($result);
for($i=0;$i<sizeof($result);$i++)
{
if($result[$i]==73)
{
//do something
}
}

まず、次のような変数で配列を取得する必要があります

$detail_array = array(); // your array
for($i=0;$i<count($detail_array);$i++)
{
  echo $detail_array[$i]->id; // you can get id
  if($detail_array[$i]->id == 73)
  {
     print_r($detail_array[$i]);
  }
}

次のように、配列を検索するにはin_arrayを試してください。

<?php
$a = array("aa","bb","cc");
if(in_array("aa",$a))
{
  echo "get it;";
  //if successful do what ever you want
}
?>
