php - 如何按月和年排列数组中的数据

Question

我正在用 php zend 框架和 sql server 2008 开发一个网站。

我需要创建一个多维数组，以这种格式按年和月存储数据：

Array(
  [2012] => Array(
      [11] => Array(           
         // data
    )
      [12] => Array(
        // data
      )

  )

  [2013] => Array(
      [01] => Array(           
         // data
    )
      [02] => Array(
        // data
      )
      [03] => Array(           
         // data
    )
      [04] => Array(
        // data
      )
  )
)

但是我的结果数组中有重复项。意味着我也在 2013 年获得 2012 年的数据。我的代码如下：

 // Database functions to get data

 function select_cldata($month,$year)
    {
      global $db;
       $select = "select ClientId,ClientName,Email,Request,'Order Placed' as info from tbl_clrequest where MONTH(CreatedDate) = ".$month." and YEAR(CreatedDate) = ".$year;
       return $db->fetchAll($select);
    }

function select_itemsdata($month,$year)
{
   global $db;
   $select = "select ItemId,ItemName,Desc,price,'Items delivered' as info1 from tbl_items where MONTH(ItemDate) = ".$month." and YEAR(ItemDate) = ".$year;
   return $db->fetchAll($select);
}

// PHP Code
$test = new dbase();
$months = "2012-11,2012-12,2013-01,2013-02,2013-03,2013-04";
$mon_num = explode(",",$months);
$res = array();
$result = array();
foreach($mon_num as $mn)
{   
    $mm = explode("-",$mn);
    $year = $mm[0];
    $month = $mm[1];
    $cl_data = $test->select_cldata($month,$year);
    $dl_data = $test->select_itemsdata($month,$year);
    $res[$month] = array_merge($clients,$sr,$events,$ses,$docs,$event_change,$devents);
    $result[$year] = $res;  
}
echo "<pre>";                               
print_r($result);die;

谁能帮帮我？

以下是我的工作示例的解决方案

foreach($mon_num as $mn)
{   
    $mm = explode("-",$mn);    
    $year = $mm[0];
    $month = $mm[1];
    $cl_data = $test->select_cldata($month,$year);
    $dl_data = $test->select_itemsdata($month,$year);
    $res = array_merge($clients,$sr,$events,$ses,$docs,$event_change,$devents);
    $result[$year][$month] = $res;  
}

我添加了一些要打印的虚拟数据

输出
