獲取數據從多維數組

我有一個PHP數組獲取數據從多維數組

我想練習/學習foreach循環在PHP。我瞭解基本的foreach。但我與多維度鬥爭。

我想讓我的每一個陣列的生日，照片名稱，照片網址，類別。

，但我不能用foreach循環正確檢索這些

用一個簡單的foreach()用於遍歷MD陣列..

foreach($yourarray['results'] as $k=>$arr) 
{ 
echo $arr['birthday']; 
echo $arr['photo']['name']; 
echo $arr['photo']['url']; 
}

比方說，你的陣列是$數據，

foreach ($data['results'] as $key => $value) 
     echo $value['birthday'];  
     echo $value['photo']['name']; 
     echo $value['photo']['url']; 
}

使用$key作爲索引值。

了']'是'後失蹤name'。 –

這是你可以訪問你的嵌套數組，無論金額類別：

// Loop over all elements of main array element 
foreach($array['results'] as $arr_key => $arr_value) { 

    // Loop over children 
    foreach($arr_value as $key => $value) { 

     // Element is array (like 'category' or 'photo') 
     if(is_array($value)) { 
      foreach($value as $sub_key => $sub_value) { 
       echo $key."[".$sub_key."] = ".$sub_value; 
      } 

     // Element is no array 
     } else { 
      echo $key." = ".$value; 
     } 
    } 
}

（Example）
