PHP set基於條件的變量

如果與下面的問題沒有關係，我很抱歉帖子標題。困惑如何給它。PHP set基於條件的變量

例I具有此數據見下表：

DEPARTMENT_ID_FK | EMAIL_ADDRESS 
001    | [email protected] 
002    | [email protected] 
001    | [email protected]

當我查詢它，是有可能設置這樣的：
如果相同DEPARTMENT_ID_FK然後顯示它作爲變量基於DEPARTMENT_ID_FK

結合值

while($dData = oci_fetch_array($q)) 
{ 
    $email = $dData['EMAIL_ADDRESS']; // I know when I echoing this variable, it will be like : [email protected]@[email protected] 
}

我要的是在循環，我們可以知道：

DEPARTMENT_ID_FK | EMAIL_ADDRESS 
001    | [email protected], [email protected] 
002    | [email protected]

任何幫助，將不勝感激。

可以讓Oracle做聚合爲你

甲骨文11

SELECT DEPARTMENT_ID_FK, 
     LISTAGG(EMAIL_ADDRESS, ',') 
      WITHIN GROUP (ORDER BY EMAIL_ADDRESS) AS EMAIL_ADDRESS 
    FROM table1 
GROUP BY DEPARTMENT_ID_FK

甲骨文10

SELECT DEPARTMENT_ID_FK, 
     RTRIM(XMLAGG(XMLELEMENT(e, EMAIL_ADDRESS, ',') 
      ORDER BY EMAIL_ADDRESS).EXTRACT('//text()').GETCLOBVAL(), ',') AS EMAIL_ADDRESS 
    FROM table1 
GROUP BY DEPARTMENT_ID_FK

這裏是一個dbfiddle演示了兩個詢問

結果：

 
DEPARTMENT_ID_FK | EMAIL_ADDRESS 
-----------------+---------------------------- 
001    | [email protected],[email protected] 
002    | [email protected] 
-----------------+----------------------------

或者只是一對夫婦的循環PHP和條件

總

$agg = []; 

while ($dData = oci_fetch_array($q)) { 
    $dep = $dData['DEPARTMENT_ID_FK']; 
    $email = $dData['EMAIL_ADDRESS']; 

    if (isset($agg[$dep])) { 
     $agg[$dep][] = $email; 
     continue; 
    } 

    $agg[$dep] = [$email]; 
} 

$result = []; 

foreach ($agg as $dep => $emails) { 
    $result[] = [ 
     'DEPARTMENT_ID_FK' => $dep, 
     'EMAIL_ADDRESS' => implode(',', $emails), 
    ]; 
} 

print_r($result);

Demo

結果：

 
Array 
(
    [0] => Array 
     (
      [DEPARTMENT_ID_FK] => 001 
      [EMAIL_ADDRESS] => [email protected],[email protected] 
     ) 

    [1] => Array 
     (
      [DEPARTMENT_ID_FK] => 002 
      [EMAIL_ADDRESS] => [email protected] 
     ) 

)

嗨peterm，感謝您的答案，但我得到的錯誤是這樣的：ORA-00923：FROM關鍵字未找到預期。我正在使用Toad –

您正在使用哪個版本的Oracle？你有沒有改變桌子的名字？ – peterm

我使用的是Oracle 10.0.2.5，是的，我已更改了我的表名 –

簡單的方式來實現自己的目標。

$email = array(); while($dData = oci_fetch_array($q)) { $email[$dData['DEPARTMENT_ID_FK']] = (isset($email[$dData['DEPARTMENT_ID_FK']]) && $email[$dData['DEPARTMENT_ID_FK']] != '' ? ', ' : '').$dData['EMAIL_ADDRESS']; } foreach ($email as $key=>$val){ echo $key . ' => '. $val; }
