多维数组提取名称多维数组

Question

我有多维数组。它可以达到N-水平。我想收集唯一的名字。从孩子名到父母。例如我需要这样

名称输出=> “运动/ Algemeen/techn.sp.ondgd/ondergoed达梅斯/运动BH”

。等级可以增加到N个数字。

[categories] => Array 
      (
       [0] => Array 
        (
         [@id] => 1 
         [name] => 78057 | Sport bh 
         [parent] => Array 
          (
           [@id] => 2 
           [name] => 7805 | ondergoed dames 
           [parent] => Array 
            (

             [name] => 780 | techn.sp.ondgd 
             [parent] => Array 
              (
               [@id] => 4 
               [name] => Algemeen 
               [parent] => Array 
                (

                 [name] => Sport

Answer 1

$arrPush = array(); 
function iterator($arr){ 
    global $arrPush; 
    foreach($arr as $key => $val){ 
     if(is_array($val)) 
      iterator($val); 
     if($key == "name"){ 
      $str = explode("|", $val); 
      $arrPush[] = isset($str[1])?$str[1]:$str[0]; 
     } 
     //filter the $key and $val here and do what you want 
    } 
} 
iterator($sweet); 
$str = implode("/", array_reverse($arrPush)); 
echo $str;

Answer 2

就像那个（没有测试）

function namify($arr) { 
    foreach($arr as $cat) { 
     if(!empty($cat['parent']) && is_array($cat['parent'])) { 
      return $cat['name'].namify($cat['parent']); 
     } else { 
      return $cat['name']; 
     } 
    } 
} 

echo namify($categories);
