php多维数组分组

Question

我有点混淆了如何基于共同的价值重新组合数组。这里是下面的数组：

Array 
(
[0] => Array 
    (
      [team] => 1 
      [id] => 5 
      [user] => teamleader1 
      [Designation] => Team Leader 
    ) 
[1] => Array 
    (
     [team] => 1 
     [id] => 6 
     [user] => consultant1 
     [Designation] => Consultant 
    ) 

[2] => Array 
    (
     [team] => 1 
     [id] => 7 
     [user] => consultant2 
     [Designation] => Consultant 
    ) 

[3] => Array 
    (
     [team] => 2 
     [id] => 8 
     [user] => consultant3 
     [Designation] => Consultant 
    ) 

[4] => Array 
    (
     [team] => 2 
     [id] => 9 
     [user] => teamleader2 
     [Designation] => Team Leader 
    ) 

) 

，我想这组由它的团队价值像下面这样：

 
Array 
(
[1] => Array 
    (
    [0] => Array(
     [team] => 1 
     [id] => 5 
     [user] =>teamleader1 
     [Designation] => Team Leader 
    ) 
    [1] => Array(
     [team] => 1 
     [id] => 6 
     [user] =>consultant1 
     [Designation] => Consultant 
    ) 
    [2] => Array(
     [team] => 1 
     [id] => 7 
     [user] =>consultant2 
     [Designation] => Consultant 
    ) 
) 
[2] => Array 
    (
    [0] => Array(
     [team] => 1 
     [id] => 8 
     [user] =>consultant3 
     [Designation] => Consultant 
    ) 
    [1] => Array(
     [team] => 1 
     [id] => 9 
     [user] =>teamleader2 
     [Designation] => Team Leader 
    ) 
    ) 
) 

两个主要的阵列组是球队本身。任何想法/帮助将不胜感激。提前致谢！

Answer 1

<?php 
$grouped = array(); 
foreach ($yourData as $item) { 
    // copy item to grouped 
    $grouped[$item['team']][] = $item; 
} 
var_dump($grouped);
