「拼合」多維數組由「組合」兒童（即：7 x 7 = 49）

我已經查找了很多類似於此的線程，但主要區別在於，在這些線程中，「children」元素只有1每個值。我的問題稍有不同：「拼合」多維數組由「組合」兒童（即：7 x 7 = 49）

你有一個2級的數組，第一級是「選項類型」（即：顏色，大小，結構等），第二級是「選項值」（即：紅色，藍色，6號，7號，皮革，棉花等）。我想將這個陣列「扁平化」成一個單一的水平陣列，它結合了選項（即：紅色 - 尺寸6-皮革，紅色 - 尺碼6-棉布，藍色 - 尺碼6-皮革等）。

因此，如果有兩個選項類型和7個選項，結果數組將有49個鍵，如果有3個選項類型和5個選項，則結果數組將有125個鍵。

@Bobot我試着實現這個作爲遞歸函數，我使用array_shift（）分隔第一個「選項類型集」，然後用剩餘的選項集調用函數，直到沒有剩下的選項集，然後將分隔的選項集與返回的「兒童套裝」。但是，我一直無法找到一個解決方案，其中所有選項集的值都處於相同的「級別」，總是會有一些額外的不需要的子數組（由於遞歸）。我一直無法提出正確的算法來完成我所需要的。 – Magnanimity

@Bobot我目前的推理是用第一組選項創建一個數組，然後在第二個遞歸中「複製」每個第二選項的內容並添加第二個選項，然後重複所有選項集，然後刪除任何鍵其中count（$ array [$ key]） Magnanimity

解

（2與每個2個選項選項類型）

function populateOptions($options,$populatedArray) 
{ 
    $optionSet = array_shift($options); 
    $returnArray = array(); 
    foreach($optionSet['option_values'] as $option) 
    { 
     foreach($populatedArray as $addedOption) 
     { 
      $addedOption[] = $option; 
      $returnArray[] = $addedOption; 
     } 
    } 

    if (!empty(count($options))) $returnArray = populateOptions($options, $returnArray); 

    return $returnArray;  
} 

$productOptions = populateOptions($optionSets,array('0' => null));
