ツリーメニューの配列の再帰関数

Question

私は2レベルのメニューのための関数を持ってください...しかし、私はどのように3つのレベルのためにそれを使用するか分からない。私を助けてくれますか？例配列

[/c300112000-zvire] => Array 
    (
     [/c300112001-pes] => Array 
      (
       [0] => /c300112005-antiparazitni-pripravky 
       [1] => /c300112002-granulovana-krmiva 
       [2] => /c300112009-hracky-misky-a-ostatni 
       [3] => /c300112003-konzervy-a-kapsicky 
       [4] => /c300112004-pamlsky-a-doplnky-stravy 
       [5] => /c300112008-psi-hygiena-a-zdravi 
      ) 

     [/c300112010-kocka] => Array 
      (
       [0] => /c300112015-antiparazitni-pripravky 
       [1] => /c300112011-granulovana-krmiva 
       [2] => /c300112017-hracky-a-misky 
       [3] => /c300112016-kocici-hygiena-a-zdravi 
       [4] => /c300112012-konzervy-a-kapsicky 
       [5] => /c300112013-pamlsky-a-doplnky-stravy 
       [6] => /c300112014-podestylky 
      ) 

     [/c300112018-mala-zvirata] => Array 
      (
       [0] => /c300112019-krmiva 
       [1] => /c300112020-steliva 
      ) 

     [/c300112021-ptactvo] => Array 
      (
       [0] => /c300112022-krmiva 
       [1] => /c300112023-steliva 
      ) 

     [/c300112024-akvaristika-a-teraristika] => Array 
      (
       [0] => /c300112025-krmiva 
      ) 

    ) 

そして、私の機能の任意の助けのための唯一の2レベルではありません3

public function saveCategoryTree($categoryTree, Eshop $eshop) 
{ 

    $em = $this->getEntityManager(); 


    for ($i = 0; $i < sizeof($categoryTree); $i++) { 
     $categoryParent = new Category(); 
     $parent = array_keys($categoryTree)[$i]; 
     $parentName = explode("/", $parent); 
     $parentName = end($parentName); 
     $categoryParent->setCreatedAt(new \DateTime()); 
     $categoryParent->setLastCheckAt(new \DateTime()); 
     $categoryParent->setLastHttpStatusCode(\Symfony\Component\HttpFoundation\Response::HTTP_OK); 
     $categoryParent->setActive(true); 
     $categoryParent->setLeaf(false); 
     $categoryParent->setEshop($eshop); 
     $categoryParent->setName($parentName); 
     $categoryParent->setLink($parent); 
     $em->persist($categoryParent); 
     $em->flush(); 


     foreach ($categoryTree[array_keys($categoryTree)[$i]] as $childItem) { 
      if (is_array($childItem)) { 
      echo "Is array ! Recursive call"; 
      } else { 
       $child = new Category(); 
       $child->setParentCategory($categoryParent); 
       $child->setCreatedAt(new \DateTime()); 
       $child->setLastCheckAt(new \DateTime()); 
       $child->setLastHttpStatusCode(\Symfony\Component\HttpFoundation\Response::HTTP_OK); 
       $child->setActive(true); 
       $child->setLeaf(true); 
       $child->setEshop($eshop); 
       $child->setName($childItem); 
       $child->setLink($childItem); 
       $em->persist($child); 
       $em->flush(); 
      } 

     } 

    } 
    exit; 
} 

おかげで作業。私の英語のために申し訳ありません。

子反復ロジックを新しい関数に移動し、再帰的に呼び出します。

このようにして、ツリー機能の2,3,4、...レイヤーで動作します。
