合併相結合的陣列，如果某些鍵/值匹配的數組

Question

比方說，我有一個數組，看起來像這樣：

Array 
(
    [0] => Array 
     (
      [id] => 44091 
      [epid] => 109912002 
      [makes] => Honda 
      [models] => Civic 
      [years] => 2000 
      [trims] => All 
      [engines] => 1.6L 1590CC 97Cu. In. l4 GAS SOHC Naturally Aspirated 
      [notes] => 
     ) 

    [1] => Array 
     (
      [id] => 77532 
      [epid] => 83253884 
      [makes] => Honda 
      [models] => Civic 
      [years] => 2000 
      [trims] => All 
      [engines] => 1.6L 1595CC l4 GAS DOHC Naturally Aspirated 
      [notes] => 
     ) 

    [2] => Array 
     (
      [id] => 151086 
      [epid] => 109956658 
      [makes] => Honda 
      [models] => Civic 
      [years] => 1999 
      [trims] => All 
      [engines] => 1.6L 1590CC 97Cu. In. l4 GAS SOHC Naturally Aspirated 
      [notes] => 
     ) 
) 

而且我想以某種方式合併/組/組合無論你怎麼稱呼它，如果具體鍵/值對匹配。

所以我的條件是：

如果讓&模型&年&修剪是一樣的，合併成1個陣列。其他鍵/值，如id/epid/trims/engines/notes不相關，如果可能的話，可以使用/繼承那些匹配條目中的1個。

一旦可能的話我想補充另一個條件也期待這個：

如果讓&模型&年&修剪&發動機是相同的組合爲1個陣列。

也許我很困惑自己，這兩個人都可以使用相同的代碼。

反正在這種情況下，我期望的結果看起來像這樣算賬：

Array 
(
    [0] => Array 
     (
      [id] => 44091 
      [epid] => 109912002 
      [makes] => Honda 
      [models] => Civic 
      [years] => 2000 
      [trims] => All 
      [engines] => 1.6L 1590CC 97Cu. In. l4 GAS SOHC Naturally Aspirated 
      [notes] => 
     ) 

    [1] => Array 
     (
      [id] => 151086 
      [epid] => 109956658 
      [makes] => Honda 
      [models] => Civic 
      [years] => 1999 
      [trims] => All 
      [engines] => 1.6L 1590CC 97Cu. In. l4 GAS SOHC Naturally Aspirated 
      [notes] => 
     ) 
) 

公告與1999年多年的排列並沒有合併。

我試圖搞亂array_unique，array_flip但無法讓它工作。

如果它很重要我使用PHP 5.6.7。

希望有人知道我在說什麼。

謝謝。

Answer 1

這可能是有益的

echo '<pre>'; 
foreach($name_of_your_array as $k=>$v){ 
    $sorted_array["$v[makes]$v[models]$v[years]$v[trims]"]=$v; 
} 
$sorted_array=array_values($sorted_array); 
print_r($sorted_array); 

輸出：

Array(
    [0] => Array 
     (
      [id] => 77532 
      [epid] => 83253884 
      [makes] => Honda 
      [models] => Civic 
      [years] => 2000 
      [trims] => All 
      [engines] => 1.6L 1595CC l4 GAS DOHC Naturally Aspirated 
      [notes] => 
     ) 

    [1] => Array 
     (
      [id] => 151086 
      [epid] => 109956658 
      [makes] => Honda 
      [models] => Civic 
      [years] => 1999 
      [trims] => All 
      [engines] => 1.6L 1590CC 97Cu. In. l4 GAS SOHC Naturally Aspirated 
      [notes] => 
     ) 

) 

Answer 2

使用作爲該鏈接陽光的建議：

php filter array values and remove duplicates from multi dimensional array

我能修改，因爲這是隻是針對單個鍵/值，它現在正在使用這個工作：

// Create dummy array for checking duplicates 
$taken = array(); 

// Loop through each item and if doesn't exist add to taken array. If exist then unset the key. 
foreach($comps as $key => $item) { 

    $string = $item['makes'] . $item['models'] . $item['years'] . $item['trims'] . $item['engines']; 

    if(!in_array($string, $taken)) { 

     $taken[] = $string; 

    } else { 

     unset($comps[$key]); 

    } 

} 

// Reindex the array 
$comps = array_values($comps);
