複数レベルの子の親組織にPHP配列を整理する

Question

配列をとり、それを親子の複数レベルの組織で編成したスニペットが見つかりました。次のように

$phases = array(
    array('id'=>1,'name'=>'First Step','parent_id'=>0,'percentage'=>.50,'order'=>1), 
    array('id'=>2,'name'=>'Second Step','parent_id'=>0, 'percentage'=>.50,'order'=>2), 
    array('id'=>3,'name'=>'Third Step','parent_id'=>2, 'percentage'=>.25,'order'=>3), 
    array('id'=>4,'name'=>'Fourth Step','parent_id'=>2, 'percentage'=>.25,'order'=>1), 
    array('id'=>5,'name'=>'Fifth Step','parent_id'=>2, 'percentage'=>.25,'order'=>1), 
    array('id'=>6,'name'=>'Sixth Step','parent_id'=>2, 'percentage'=>.25,'order'=>1), 
    ); 

親指の下にすべての子配列を追加することができました。私はそれのためのコードを見つけることができません。誰もがあなたがで終わるしようとしているものの構造

Answer 1

<?php 
$phases = array(
    array('id'=>1,'name'=>'First Step','parent_id'=>0,'percentage'=>.50,'order'=>1), 
    array('id'=>2,'name'=>'Second Step','parent_id'=>0, 'percentage'=>.50,'order'=>2), 
    array('id'=>3,'name'=>'Third Step','parent_id'=>2, 'percentage'=>.25,'order'=>3), 
    array('id'=>4,'name'=>'Fourth Step','parent_id'=>2, 'percentage'=>.25,'order'=>1), 
    array('id'=>5,'name'=>'Fifth Step','parent_id'=>2, 'percentage'=>.25,'order'=>1), 
    array('id'=>6,'name'=>'Sixth Step','parent_id'=>2, 'percentage'=>.25,'order'=>1), 
    //just to add levels 
    array('id'=>7,'name'=>'7th Step','parent_id'=>5, 'percentage'=>.25,'order'=>1), 
    array('id'=>8,'name'=>'8th Step','parent_id'=>6, 'percentage'=>.25,'order'=>1) 
    ); 

$treearr = array('0' => array('children'=> array())); 
foreach($phases as $phase){ 
    if(!isset($treearr[$phase['id']]['children'])) $phase['children'] = $treearr[$phase['id']]['children']; 
    $treearr[$phase['id']] = $phase; 
    if(!isset($treearr[$phase['parent_id']])) $treearr[$phase['parent_id']] = array('children'=> array()); 
    $treearr[$phase['parent_id']]['children'][] = &$treearr[$phase['id']]; 
} 
$tree = $treearr[0]; 
unset($treearr); 
var_dump($tree); 

Answer 2

注かなり確実なアイデアを持っているが、多分これはあなたが始められるでしょう：

$multidim = array(); 
$multidim[0] = array(); 

foreach ($phases as $phase) { 
    $multidim[$phase['id']] = array(
     'name' => $phase['name'], 
     'children' => array(), 
     'percentage' => $phase['percentage'], 
     'parent_id' => $phase['parent_id'] 
    ); 
    $multidim[$phase['parent_id']]['children'][] = $phase['id']; 
} 

それとも、何かしたいです：

$phases[0][2][3] = array('name' => 'Third Step', 'percentage' => 0.25, 'order' => 3);
