'、「untree」再帰的な配列を平らにINGの

Question

I持っ配列、私は、別の項目に子供-ノードを 『カット』私にこれらの配列を与えることによって、 『フラット化』したい

$arr = Array(
    Array(
     'title' => 'Title 1', 
     'id' => 1, 
     'parent' => 0, 
     'children' => [ 
      Array(
       'title' => 'Title 1.1', 
       'id' => 4, 
       'parent' => 1, 
       'children' => [ 
        Array(
        'title' => 'Title 1.1.1', 
        'id' => 19, 
        'parent' => 4 
        ),  
        Array(
        'title' => 'Title 1.1.2', 
        'id' => 123, 
        'parent' => 4 
        ) 
       ] 
      ), 
      Array(
       'title' => 'Title 1.2', 
       'id' => 4, 
       'parent' => 1, 
       'children' => [ 
        Array(
        'title' => 'Title 1.2.1', 
        'id' => 19,

     'title' => 'Title 2', 
     'id' => 1, 
     'parent' => 0 
    ) 
); 

1レベル配列のアイテム：

$arr = Array(
    Array(
     'title' => 'Title 1',

ここで誰かを助けることができますか？どうもありがとう！

これがお手伝いします。..

<?php 
function recursiveFind(array $items,&$return=array()) 
{ 
    foreach($items as $item){ 
     if(array_key_exists('children',$item)){ 
      $childs = $item['children']; 
      unset($item['children']); 
      array_push($return,$item); 
      recursiveFind($childs,$return); 

     }else{ 
      array_push($return,$item); 
     } 

    } 
    return $return; 
} 

$arr = Array(
    Array(
     'title' => 'Title 1', 
     'id' => 1, 
     'parent' => 0, 
     'children' => [ 
      Array(
       'title' => 'Title 1.1', 
       'id' => 4, 
       'parent' => 1, 
       'children' => [ 
        Array(
        'title' => 'Title 1.1.1', 
        'id' => 19, 
        'parent' => 4 
        ),  
        Array(
        'title' => 'Title 1.1.2', 
        'id' => 123, 
        'parent' => 4 
        ) 
       ] 
      ), 
      Array(
       'title' => 'Title 1.2', 
       'id' => 4, 
       'parent' => 1, 
       'children' => [ 
        Array(
        'title' => 'Title 1.2.1', 
        'id' => 19, 
        'parent' => 4 
        ) 
       ] 
      ) 
     ] 
    ), 
    Array(
     'title' => 'Title 2', 
     'id' => 1, 
     'parent' => 0 
    ) 
); 
echo '<pre>'; 
print_r(recursiveFind($arr));

3のforeachでこれを試してみてください：

foreachのを（$編曲：$ Aなど） {

echo $a['title']; 
foreach($a['children'] as $b) 
{ 
    echo $b['title']; 
    foreach($b['children'] as $c) 
    { 
     echo $c['title']; 
    } 
} 

}
