动态构建多维数组

Question

如何动态构建多维数组？

我知道这是一个开放式的问题，但我有一段时间了。

我所拥有的是一个数组需要使数组添加另一个子节点的可能性。

Array(
[0] => Array
    (
        [parentID] => 0
        [component] => 23941/01  
        [decoration] =>          
        [hasChild] => T
        [proccessed] => T
        [cmp0] => Array
            (
                [parentID] => 0
                [component] => COLC01    
                [decoration] =>          
                [hasChild] => F
                [proccessed] => T
            )

        [cmp1] => Array
            (
                [parentID] => 0
                [component] => PPH   
                [decoration] =>          
                [hasChild] => F
                [proccessed] => T
            )

    )

[1] => Array
    (
        [parentID] => 1
        [component] => 23930/20SB
        [decoration] =>          
        [hasChild] => T
        [proccessed] => T
        [cmp0] => Array
            (
                [parentID] => 1
                [component] => 23930/20  
                [decoration] =>          
                [hasChild] => T
                [proccessed] => F
            )

    )

[2] => Array
    (
        [parentID] => 2
        [component] => SC070400SB
        [decoration] =>          
        [hasChild] => T
        [proccessed] => T
        [cmp0] => Array
            (
                [parentID] => 2
                [component] => SC070400  
                [decoration] =>          
                [hasChild] => F
                [proccessed] => T
            )

    ))

我使用简单数组推送生成的外部数组[0,1,2]。当我开始遍历数组以达到较低级别时，我遇到的问题不仅仅是深层了。

这是我的主要问题：如何动态添加元素到数组，同时仍然能够检查键值以查看是否应该更深入？ processed和hasChild标志告诉我可以更深入，但isset和array_key_exists似乎不适用于新添加的元素。事实上，当我将数组打印到屏幕时，它甚至没有显示任何元素，如[cmp0] ...

我不确定我的代码会提供多少帮助，但我会在此处进行浏览。

function explodeBOM(&$BOMArray,$library,$sonar){        
    $saveKey = '';
    $childCounter = 0;
    $childKey = '';
    foreach($BOMArray as &$bomLine){  
        $childKey = 'cmp' . (string)$childCounter;
        while(array_key_exists($childKey,$bomLine)){                
            explodeBOM($bomLine[$childKey],$library,$sonar);
        }
        if($bomLine['proccessed'] == "F"){
             $saveKey = $bomLine['parentID'];
             $bomItems = getBOM($bomLine['component'],$bomLine['decoration'],$library,$sonar);
             foreach($bomItems as $newBomLine){
                 $itemMasterInfo = getItemMasterInfo($newBomLine['BMCMP#'],$newBomLine['BMCMD#'],$library,$sonar);
                 if($itemMasterInfo['ITPRTC'] != 'P' AND $itemMasterInfo['ITPRTC'] != 'C'){            
                    // add it to the array                        
                    $componetArray = array();
                    $componetArray['parentID'] = $saveKey;
                    $componetArray['component'] = $newBomLine['BMCMP#'];
                    $componetArray['decoration'] = $newBomLine['BMCMD#'];
                    $componetArray['hasChild'] = parentOrChildBOM($newBomLine['BMCMP#'],$newBomLine['BMCMD#'],$library,$sonar);
                    if ($componetArray['hasChild'] == 'F'){
                        $componetArray['proccessed'] = 'T';                        
                    }else{
                        $componetArray['proccessed'] = 'F';                    
                    }                        
                    //array_push($bomLine,$componetArray);
                    $childKey = 'cmp' . (string)$childCounter;
                    $childCounter++;
                    $bomLine[$childKey] = $componetArray;
                    $bomLine['proccessed'] = 'T';

                    reset($BOMArray);
                 }
             }
             $childCounter = 0;
         } 
     }            
}
