    'language' => 
    array (

    'language' => 
    array (
    'code' => 'en', 
    'name' => 'English', 
), 
));

正如你可能已經注意到，在上述陣列印度被提及兩次，現在，我要的是，如果兩個或更多陣列包含相同的國家，那麼所有包含在同一個國家的數組成爲一個陣列是這樣的：

$arr = array (array (
    'country' => 
    array (
    'code' => 'in', 
    'name' => 'India', 
), 
    'language' => array(
    array (
    'code' => 'en', 
    'name' => 'English', 
), 
    array (
    'code' => 'hi', 
    'name' => 'Hindi', 
), 
) 
) 
);

和陣列的其餘部分保持原樣。

你舉的例子的情況是非常大的;你能提供一個你想要做的最簡單的例子嗎？ – Vulcan

我投票結束這個問題作爲題外話，因爲SO不是衆包代碼生成器。 –

謝謝！當我第一次嘗試你的代碼時，它不起作用，但現在當我重試時，我發現它確實有效，也許我做錯了什麼。再次感謝！ – harry123

樂意幫忙:) – Anders

我發現多了一個解決方案，但是@anders代碼也在努力！

$res = array(); 

foreach($arr as $val) 
{ 
    if(!isset($res[$val['country']['name']])) 

    $res[$val['country']['name']] = array('code'=>$val['country']['code'], 'name'=>$val['country']['name'], 'language'=>array()); 

    $res[$val['country']['name']]['language'][] = array('code'=>$val['language']['code'], 'name'=>$val['language']['name']); 
} 
echo "<pre>"; 
print_r(var_export(array_values($res))); 
echo "</pre>";

Here is a demo of working example.
