如何获得数组组如果值存在

Question

我有一个像这样的数组和php我放在循环中的数组。

Array 
(
    [0] => Array 
     (
      [topic_id] => 973 
      [reply_id] => 3549 
      [user_id] => 1 
     ) 

    [1] => Array 
     (
      [topic_id] => 973 
      [reply_id] => 3551 
      [user_id] => 1 
     ) 

    [2] => Array 
     (
      [topic_id] => 973 
      [reply_id] => 3553 
      [user_id] => 1 
      [status] => 1 
     ) 

    [3] => Array 
     (
      [topic_id] => 973 
      [reply_id] => 3555 
      [user_id] => 1 
      [status] => 1 
     ) 

    [4] => Array 
     (
      [topic_id] => 973 
      [reply_id] => 4401 
      [reply_author] => 28 
      [user_id] => 1 
      [status] => 1 
     ) 

    [5] => Array 
     (
      [topic_id] => 232 
      [reply_id] => 4405 
      [reply_author] => 28 
      [user_id] => 1 
      [status] => 1 
     ) 

) 

现在环项目有唯一的ID和ID相同像reply_id在阵列。我想根据reply_id拆分每个阵列组。

所以，最后的结果，我想是这样的：

环项目1（编号：3549）

Array 
(
    [topic_id] => 973 
    [reply_id] => 3549 
    [user_id] => 1 
) 

---

环项目2（编号：3551）

Array 
(
    [topic_id] => 973 
    [reply_id] => 3551 
    [user_id] => 1 
) 

---

和更多...

如何使它，请帮助。

编辑：第一次回复后我现在想我明白你的意思了。

$myListWithIds = array('3549','3551'); 
$idListCount = 2; 

for($x = 0; $x < $idListCount; $x++) 
{ 
    $key = array_search($myListWithIds[$x], array_column($myArray, 'reply_id')); 
    echo "<pre>"; 
    print_r($myArray[$key]); 
    echo "</pre>"; 
} 

假设你的数组存储在变量$ myArray中。
