需要得到的數據對於一個特定的列在一個陣列

Question

我只需要在一個array..below打印的數據是我的數組

Array (
    [sales_data] => Array (
     [0] => Array (
      [dealer] => DS949 
      [value] => 35 
      [mod_id] => s01 
      [month] => Oct 
      [year] => 16 
     ), 
     [1] => Array (
      [dealer] => DS950 
      [value] => 80 
      [mod_id] => s01 
      [month] => Oct 
      [year] => 16 
     ), 
     [2] => Array (
      [dealer] => DS949 
      [value] => 25 
      [mod_id] => s01 
      [month] => Sep 
      [year] => 16 
     ), 
     [3] => Array (
      [dealer] => DS950 
      [value] => 55 
      [mod_id] => s01 
      [month] => Sep 
      [year] => 16 
     ) 
    ) 
) 

見上文陣列顯示其每月月兩次和九月2但經銷商是不同的，價值是不同的，所以，我需要一個數組中的10月數據和兩個月的一個數組中的9月數據。

Array (
    [sales_data] => Array (
     [0] => Array (
      [dealer] => DS949 
      [value] => 35 
      [dealer] => DS950 
      [value] => 80 
      [mod_id] => s01 
      [month] => Oct 
      [year] => 16 
     ), 
     [1] => Array (
      [dealer] => DS949 
      [value] => 25 
      [dealer] => DS950 
      [value] => 55 
      [mod_id] => s01 
      [month] => Sep 
      [year] => 16 
     ) 
    ) 
) 

這裏是我的代碼：

$all_custom_data = $this->front_model->get_period_data($mod_id,$month,$year,$manu,$city); 
    array_push($all_custom_dataarr, $all_custom_data); 
} 
$arrFinal=array(); 
$i=0; 
$month=array(); 
foreach($all_custom_dataarr as $custom_data1){ 
    foreach($custom_data1 as $custom_data){ 
     $month[]=$custom_data->month; 
     $arrFinal[$i]['dealer']=$custom_data->dealer; 
     $arrFinal[$i]['value']=$custom_data->value; 
     $arrFinal[$i]['mod_id']=$custom_data->mod_id; 
     $arrFinal[$i]['month']=$custom_data->month; 
     $arrFinal[$i]['year']=$custom_data->year; 
     $i++; 
    } 
} 

$data['sales_data']=array_unique($arrFinal, SORT_REGULAR); 
print_r($data);

Amrinder，我覺得這是組織陣列，這樣就可以刪除重複，容易在將來訪問數組的最佳方式。

$all_custom_dataarr=array(
    "sales_data"=>array(
     0=>array(
      "dealer"=>"DS949", 
      "value"=>"35", 
      "mod_id"=>"s01", 
      "month"=>"Oct", 
      "year"=>"16" 
     ), 
     1=>array(
      "dealer"=>"DS950", 
      "value"=>"80", 
      "mod_id"=>"s01", 
      "month"=>"Oct", 
      "year"=>"16" 
     ), 
     2=>array(
      "dealer"=>"DS949", 
      "value"=>"25", 
      "mod_id"=>"s01", 
      "month"=>"Sep", 
      "year"=>"16" 
     ), 
     3=>array(
      "dealer"=>"DS950", 
      "value"=>"55", 
      "mod_id"=>"s01", 
      "month"=>"Sep", 
      "year"=>"16" 
     ) 
    ) 
); 

foreach($all_custom_dataarr["sales_data"] as $array){ 
    $new_array[$array["year"]][$array["month"]][$array["dealer"]]["mod_id"]=$array["mod_id"]; 
    $new_array[$array["year"]][$array["month"]][$array["dealer"]]["value"]=$array["value"]; 
} 

echo "<pre>"; 
var_export($new_array); 
echo "</pre>"; 

產量...

$new_array = array(
       16 => array(
        'Oct' => array(
         'DS949' => array('mod_id'=>'s01','value'=>'35'), 
         'DS950' => array('mod_id'=>'s01','value'=>'80') 
        ), 
        'Sep' => array(
         'DS949' => array('mod_id'=>'s01','value'=>'25'), 
         'DS950' => array('mod_id'=>'s01','value'=>'55'), 
        ), 
       ), 
      ); 

此數組結構允許用戶在邏輯組值和子陣列使用的唯一密鑰。

如果有任何重複的year-month-dealer-mod_id或year-month-dealer-value值，它們將覆蓋較早的值（作爲在foreach循環中構建新數組的結果）。

如果您有多年，或多個月或多個經銷商，數據將被分開 並且由於新的關聯密鑰名稱而易於訪問。

例如，如果您特別想知道的16Oct爲DS950的mod_id和value值使用：

$new_array["16"]["Oct"]["DS950"]["mod_id"]和$new_array["16"]["Oct"]["DS950"]["value"]

或

foreach($new_array["16"]["Oct"]["DS950"] as $key=>$value){ 
    echo "$key = $value<br>"; 
}
