$sizeofdims = sizeof($keys); 
$main_key = $keys[0]; 


echo '<pre>'; 

foreach ($arr[$main_key] as $main_item) 
{ 
    $key_handle = $main_item; 
    echo "$key_handle\n"; 

    foreach ($keys as $i=>$k) 
    { 
     if ($k == $main_key) 
     { 
      continue; 
     } 

     foreach ($arr[$k] as $item) 
     { 
      $key_current = $key_handle; 
      $key_handle .= $delimiter.$item; 
      echo "$key_handle\n"; 

      if ($i+1 == $sizeofdims) 
      { 
       $key_handle = $key_current; 
      } 
      else 
      { 
       break;

Answer 1

冗談のために私は最も簡単な解決法を提供します：

foreach ($arr[$keys[0]] as $brand) { 
    echo $brand . "\n"; 
    foreach ($arr[$keys[1]] as $country) { 
     echo $brand . '#' . $country . "\n"; 
     foreach ($arr[$keys[2]] as $method) { 
      echo $brand . '#' . $country . '#' . $method . "\n"; 
     } 
    } 
} 

しかし、次に自分で試してみてください。

Answer 2

あなたのアレイは動作するのが少し難しいです。私はそれを多次元配列に再編成することをお勧めします。

$array = array(
    'LG' => array(
     'Neverland' => array('Pirate gold', 'Magic coins', 'Fairy dust'),),) 
     'Fantasia' => array('Gems', 'Dragon Heartstring', 'Old underwear'),), 
    ), 
    'Sony' => array(
     'Neverland' => array('Pirate gold', 'Magic coins', 'Fairy dust'),),) 
     'Fantasia' => array('Gems', 'Dragon Heartstring', 'Old underwear'),), 
    ), 
); 

今、あなたは、次のループに

foreach ($array as $brand => $countries) { 
    echo $brand."<br />"; 
    foreach ($countries as $country => $paymentMethods) { 
     echo $brand."#".$country."<br />"; 
     foreach ($paymentMethods as $paymentMethod) { 
      echo $brand."#".$country."#".$paymentMethod."<br />"; 
     } 
    } 
}
