如何將數組元素轉換爲PHP中的simplae元素？

我的問題聽起來有些笨拙，但這正是我想要做的。我有一個從SQL查詢獲得的名爲$data的數組。爲了您的參考，我把它放在前面兩個元素：如何將數組元素轉換爲PHP中的simplae元素？

Array 
(
    [0] => Array 
     (
      [test_pack_id] => 9f27643023a83addd5eed41c4aade840 
      [test_pack_name] => Bank Exams Complete Combo 
      [test_pack_desc] => This Package contains 24 tests of Reasoning, English and Quantitative Aptitude + 2 Mega tests of all 3 subjects. 

Total Tests in this Package : 26 
      [test_pack_type_id] => 3 
      [test_pack_image] => 
      [test_pack_validity_year] => 0 
      [test_pack_validity_month] => 3 
      [test_pack_validity_days] => 0 
      [test_pack_plan] => paid 
      [test_pack_price] => 399.00 
      [test_pack_no_tests] => 0 
      [test_pack_publish] => yes 
      [test_pack_sold] => 1 
      [test_pack_created_staff_id] => ff8d4a5ea6bf11dce105aa2fa7b959b8 
      [test_pack_updated_staff_id] => 81c4e3607c7e56bbf5461ef150437675 
      [test_pack_created_date] => 1347127051 
      [test_pack_updated_date] => 1349235701 
      [test_pack_purchase_date] => 1351228594 
     ) 

    [1] => Array 
     (
      [test_pack_id] => e7e95de96987cc7c89c1f0183110fb38 
      [test_pack_name] => Bank Reasoning 
      [test_pack_desc] => This package contains 8 tests on Reasoning. 
      [test_pack_type_id] => 3 
      [test_pack_image] => 
      [test_pack_validity_year] => 0 
      [test_pack_validity_month] => 3 
      [test_pack_validity_days] => 0 
      [test_pack_plan] => free 
      [test_pack_price] => 0.00 
      [test_pack_no_tests] => 0 
      [test_pack_publish] => yes 
      [test_pack_sold] => 4 
      [test_pack_created_staff_id] => ff8d4a5ea6bf11dce105aa2fa7b959b8 
      [test_pack_updated_staff_id] => ff8d4a5ea6bf11dce105aa2fa7b959b8 
      [test_pack_created_date] => 1347127196 
      [test_pack_updated_date] => 1347127387 
      [test_pack_purchase_date] => 1363775709 
     ) 
)

現在我要在這個數組中插入一個新的鍵值對。爲此，我向數據庫發出一個查詢。該查詢將針對數組$data的每個元素進行觸發。它的代碼如下：

foreach($data as $data1) { 

      $sql = " SELECT COUNT(*) as package_count FROM ". TBL_USER_PACKAGES. " WHERE pack_id ='".$data1['test_pack_id']."' AND pack_assign_date "; 
      $sql .= " BETWEEN UNIX_TIMESTAMP(CURDATE()) and UNIX_TIMESTAMP(DATE_ADD(CURDATE(),INTERVAL 1 day)) "; 
      $this->mDb->Query($sql); 
      $data1['package_sold_count'] = $this->mDb->FetchArray(MYSQL_FETCH_SINGLE); 
}

但是，當我訪問該查詢的結果，我得到它在這樣的陣列格式：

Array(
[0] => Array 
     (
      [test_pack_id] => 9f27643023a83addd5eed41c4aade840 
      [test_pack_name] => Bank Exams Complete Combo 
      [test_pack_desc] => This Package contains 24 tests of Reasoning, English and Quantitative Aptitude + 2 Mega tests of all 3 subjects. 

Total Tests in this Package : 26 
      [test_pack_type_id] => 3 
      [test_pack_image] => 
      [test_pack_validity_year] => 0 
      [test_pack_validity_month] => 3 
      [test_pack_validity_days] => 0 
      [test_pack_plan] => paid 
      [test_pack_price] => 399.00 
      [test_pack_no_tests] => 0 
      [test_pack_publish] => yes 
      [test_pack_sold] => 1 
      [test_pack_created_staff_id] => ff8d4a5ea6bf11dce105aa2fa7b959b8 
      [test_pack_updated_staff_id] => 81c4e3607c7e56bbf5461ef150437675 
      [test_pack_created_date] => 303 
      [test_pack_updated_date] => 1349235701 
      [test_pack_purchase_date] => 256 
      [package_sold_count] => Array 
       (
        [package_count] => 4 
       ) 
[1] => Array 
     (
      [test_pack_id] => e7e95de96987cc7c89c1f0183110fb38 
      [test_pack_name] => Bank Reasoning 
      [test_pack_desc] => This package contains 8 tests on Reasoning. 
      [test_pack_type_id] => 3 
      [test_pack_image] => 
      [test_pack_validity_year] => 0 
      [test_pack_validity_month] => 3 
      [test_pack_validity_days] => 0 
      [test_pack_plan] => free 
      [test_pack_price] => 0.00 
      [test_pack_no_tests] => 0 
      [test_pack_publish] => yes 
      [test_pack_sold] => 4 
      [test_pack_created_staff_id] => ff8d4a5ea6bf11dce105aa2fa7b959b8 
      [test_pack_updated_staff_id] => ff8d4a5ea6bf11dce105aa2fa7b959b8 
      [test_pack_created_date] => 303 
      [test_pack_updated_date] => 1347127387 
      [test_pack_purchase_date] => 110 
      [package_sold_count] => Array 
       (
        [package_count] => 2 
       ) 
)

其實我想要的數組作爲新的鍵值對，而不是新的關聯數組，如下所示：

Array(
    [0] => Array 
      (
       [test_pack_id] => 9f27643023a83addd5eed41c4aade840 
       [test_pack_name] => Bank Exams Complete Combo 
       [test_pack_desc] => This Package contains 24 tests of Reasoning, English and Quantitative Aptitude + 2 Mega tests of all 3 subjects. 

    Total Tests in this Package : 26 
       [test_pack_type_id] => 3 
       [test_pack_image] => 
       [test_pack_validity_year] => 0 
       [test_pack_validity_month] => 3 
       [test_pack_validity_days] => 0 
       [test_pack_plan] => paid 
       [test_pack_price] => 399.00 
       [test_pack_no_tests] => 0 
       [test_pack_publish] => yes 
       [test_pack_sold] => 1 
       [test_pack_created_staff_id] => ff8d4a5ea6bf11dce105aa2fa7b959b8 
       [test_pack_updated_staff_id] => 81c4e3607c7e56bbf5461ef150437675 
       [test_pack_created_date] => 303 
       [test_pack_updated_date] => 1349235701 
       [test_pack_purchase_date] => 256 
       [package_sold_count] => 4 

)

任何人都可以幫助我實現這個目標嗎？提前致謝。

東西如下面所示，簡單應該可以正常工作，做你想做什麼：

<?php 
    foreach ($array as &$subArray) { 
     $subArray["package_sold_count"] = $subArray["package_sold_count"]["package_count"]; 
    } 
    unset($subArray); 
?>

或者乾脆設置不同，當你給它分配：

foreach($data as $data1) { 

      $sql = " SELECT COUNT(*) as package_count FROM ". TBL_USER_PACKAGES. " WHERE pack_id ='".$data1['test_pack_id']."' AND pack_assign_date "; 
      $sql .= " BETWEEN UNIX_TIMESTAMP(CURDATE()) and UNIX_TIMESTAMP(DATE_ADD(CURDATE(),INTERVAL 1 day)) "; 
      $this->mDb->Query($sql); 

      //First assign a variable 
      $dbFetch = $this->mDb->FetchArray(MYSQL_FETCH_SINGLE); 

      //Then refer to it 
      $data1['package_sold_count'] = $dbFetch["package_count"]; 
}

當你獲取新的密鑰/值對：

$data1['package_sold_count'] = $this->mDb->FetchArray(MYSQL_FETCH_SINGLE);

你實際上正在獲取一個數組，即使它只是o ne元素，這就是你所看到的。

相反，這樣做：

$temp = $this->mDb->FetchArray(MYSQL_FETCH_SINGLE); 
$data1['package_sold_count'] = $temp['package_count']; // assumes associative array

這可能工作過，但我偶爾有麻煩包裝代碼起來得太緊。

$data1['package_sold_count'] = $this->mDb->FetchArray(MYSQL_FETCH_SINGLE)['package_count'];
