從單個陣列構建多維

Question

大綱

，花2天嘗試得到這個工作後...

解決方案

我想調整自己的數組多維數組具有以下結構：

Level 1 -> All level 1s 
     Level 2 -> All level 2s 
       Level 3 -> Each level Three Item 
       Level 3 -> Each level Three Item 
     Level 2 -> All level 2s 
       Level 3 -> Each level Three Item 
       Level 3 -> Each level Three Item 
Level 1 -> All level 1s 
     Level 2 -> All level 2s 
       Level 3 -> Each level Three Item 
       Level 3 -> Each level Three Item 
     Level 2 -> All level 2s 
       Level 3 -> Each level Three Item 
       Level 3 -> Each level Three Item 

數據

數據按我需要的順序編寫。例如，直接在Level 1之下的所有level 2應位於其父代Level 1之內，直到數據中出現下一個Level 1。這應該與Level 2和3相同。基本上，直到更高的數字出現，它應該開始一個新的行。

我有很多不同的值，下面的數據只是一個例子。在陣列level裏面指出它應該在哪個級別。

Answer 1

您可以嘗試使用PHP鏈接operator &，嘗試財產以後這樣的：

$collection = array(); 
    $list = yourArray[]; 
    foreach ($list as $item) { 
     if (isset($list[$item['key']])) { 
     $list[$item['key']]['levels'][$item['key']] =& $list[$item['key']]; 
     } else { 
     $collection[$item['key']] =& $list[$item['key']]; 
     } 
    } 

第二個變體

$row = array(); 
if (is_array($source) && !empty($source)) { 
    foreach ($source as $item) { 
     if (!isset($row[$item['level']])) { 
      $row[$item['level']] = array($item['level']); 
      $row[$item['level']]['parent'] = $item['level'] - 1; 
     } 
     if(isset($row[$item['level']])){ 
      $row[$item['level']]['child'][$item['key']] = $item; 
     } 
    } 
    if(!empty($row)){ 
     foreach($row as $rowK => $rowV){ 
      if(isset($row[$rowV['parent']])){ 
       $row[$rowV['parent']]['level-' . $rowK][] =& $row[$rowK]; 
      } else { 
       $collection[$rowK] =& $row[$rowK]; 
      } 
     } 
    } 
} 

Answer 2

這就是我想出了......這不是一個非常有效的方法，但也許有人可以把它變成一個花哨的遞歸函數，使其抽象 - 我試了一下，但我真的吸食遞歸：-P

function cascade_array ($array, $current_level = 1) { 

    // filter only the array elements with the level==current_level 
    $chunks = array_filter ($array, function ($v) use ($current_level) { 
     return $v['level'] == 1; } 
    ); 

    // extract the keys from those elements an put them in reverse order 
    $splice_keys = array_reverse(array_keys($chunks)); 

    // now splice the array at those keys and put the 
    // array-parts in a result-array, so you have an array of e.g. all level1 
    foreach ($splice_keys as $offset) { 

      $results[] = array_splice($array, $offset); 
    } 

    //now walk through the results and basically do the same 
    foreach($results as &$level) { 

     $level[0]['children'] = array(); 

     $array = array_splice($level, 1); 
     $chunks = array_filter ($array, function ($v) use ($current_level) { 
      return $v['level'] == 2; } 
     ); 
     $splice_keys = array_reverse(array_keys($chunks)); 

     foreach($splice_keys as $offset) { 

      $level[0]['children'][] = array_splice($array, $offset); 

     } 


     foreach($level[0]['children'] as &$child_level) { 

      $child_level[0]['children'] = array(); 

      $array = array_splice($child_level, 1); 
      $chunks = array_filter ($array, function ($v) use ($current_level) { 

       return $v['level'] == 3; } 
      ); 
      $splice_keys = array_reverse(array_keys($chunks)); 

      foreach($splice_keys as $offset) { 

       $child_level[0]['children'][] = array_splice($array, $offset); 

      } 

     } 

    } 

    return $results; 

} 

該代碼實際上非常簡單，我猜。下面是一個工作示例：http://codepad.viper-7.com/kb5JBc - 我希望它有幫助:)

遞歸實體從來都不是一件容易的事情，尤其是如果您剛開始使用PHP時。

以下是一個簡短的函數，它避免了通過使用php引用來使用遞歸函數的需要。引用可能會引起混淆，因爲遞歸也是如此。最好的建議是閱讀並嘗試一些事情，以便弄清楚他們的行爲。

以下作品使用一個跟蹤關卡的堆棧，並繼續返回最後一級以查找最新的父級。

function stackItems($items){ 
    $level = 0; 
    $return = array(); 
    $stack = array(&$return); 
    foreach ($items as $key => $item) { 
    while ($level >= $item['level']) { 
     unset($stack[$level--]); 
    } 
    $parent = &$stack[$level]; 
    if (!isset($parent['children'])) { 
     $parent['children'] = array(); 
    } 
    $parent['children'][] = &$items[$key]; 
    if ($item['level'] > $level) { 
     $level = $item['level']; 
     $stack[$level] = &$items[$key]; 
    } 
    } 
    return $return['children']; 
} 

有註解的版本：

function stackItems($items){ 
    $level = 0; 
    $return = array(); 
    /// build our stack with our return array as first item 
    $stack = array(&$return); 
    /// step each item 
    foreach ($items as $key => $item) { 
    /// if our next item is lower down than current 
    /// level, drop the stack down. 
    while ($level >= $item['level']) { 
     /// we may as well unset to clear memory 
     unset($stack[$level--]); 
    } 
    /// create a shortcut reference to our parent on the stack 
    $parent = &$stack[$level]; 
    /// to avoid warnings create the children array first 
    if (!isset($parent['children'])) { 
     $parent['children'] = array(); 
    } 
    /// now add ourselves to the current parent on the stack 
    $parent['children'][] = &$items[$key]; 
    /// if our current item is higher level than current, add to 
    /// the stack ready to be treated as the next parent. 
    if ($item['level'] > $level) { 
     /// level ourselves to the current item 
     $level = $item['level']; 
     /// store in the stack a reference to item 
     $stack[$level] = &$items[$key]; 
    } 
    } 
    /// return the first set of children as there seems 
    /// to be only one level 1 item. 
    return $return['children']; 
}
