PHPグループ多次元配列

Question

私はこのような単純な二次元配列を持っている：

Array 
(
    [0] => Array 
     (
      [id] => 1 
      [name] => John 
      [company] => One 
      [price] => 12.22 
     ) 

    [1] => Array 
     (
      [id] => 1 
      [name] => John 
      [company] => Two 
      [price] => 14.33 
     ) 
    [2] => Array 
     (
      [id] => 2 
      [name] => Mike 
      [company] => One 
      [price] => 15.11 
     ) 
    [3] => Array 
     (
      [id] => 2 
      [name] => Mike 
      [company] => Two 
      [price] => 10.12 
     ) 

    [4] => Array 
     (
      [id] => 3 
      [name] => Paul 
      [company] => One 
      [price] => 42.22 
     ) 
    [5] => Array 
     (
      [id] => 3 
      [name] => Paul 
      [company] => Two 
      [price] => 56.62 
     ) 
    [6] => Array 
     (
      [id] => 3 
      [name] => Paul 
      [company] => Three 
      [price] => 16.12 
     ) 
) 

私はその後、別の値を持つ配列を作成し、グループidとnameに必要なこのような何か：

Array 
(
    [0] => Array 
     (
      [id] => 1 
      [name] => John 
      [companies] => array (
            array(
             [company] => One 
             [price] => 12.22 
           ) 
            array(
             [company] => Two 
             [price] => 14.33 
           ) 
          )    
     ) 

    [1] => Array 
     (
      [id] => 2 
      [name] => Mike 
      [companies] => array (
            array(
             [company] => One 
             [price] => 15.11 
           ) 
            array(
             [company] => Two 
             [price] => 10.12 
           ) 
          )    
     ) 
    [2] => Array 
     (
      [id] => 3 
      [name] => Paul 
      [companies] => array (
            array(
             [company] => One 
             [price] => 42.22 
           ) 
            array(
             [company] => Two 
             [price] => 56.62 
           ) 
            array(
             [company] => Three 
             [price] => 16.12 
           ) 
          )    
     )   
) 

を

PHPで行う最良の方法は何ですか？

これは私のattempです：

<?php 
$items=array(); 
$temp = 0; 
$companies = array('uno','dos','tres'); 
foreach ($values as $value) { 

    if ($temp == $value['id']) 
    continue;        
    else 
    $temp == $value['id']; 

    foreach ($companies as $key => $company){ 
    foreach ($values as $item){ 
     if ($item['id'] == $temp && $item['company'] == $key) 
     $value['company'][$key] = $item['price']; 
    } 
    } 

    $items[] = $value; 

} 

Answer 1

は、あなたがする必要がある場合は、すぐ隣companyとprice

foreach($array as $v) { 
    $result[$v['id']]['id']   = $v['id']; 
    $result[$v['id']]['name']  = $v['name']; 
    $result[$v['id']]['companies'][] = array('company' => $v['company'], 
              'price' => $v['price']); 
} 

で新しい配列を追加し、新しい配列のキーとしてidを使用しますそれを再インデックスする（恐らくそうではない）：

$result = array_values($result);
