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

就像那個（沒有測試）

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);
