如何訪問多維數組中的值並在循環中激發查詢？

我有一個名爲$user_study_test_packages的多維數組。爲了您的參考，我正在打印整個陣列。如何訪問多維數組中的值並在循環中激發查詢？

現在我想火從內array.The演示SQL查詢各[pack_id]一個SQL查詢一個單一[pack_id]值被賦予如下：

SELECT package_type.package_type_name 
FROM package_type 
JOIN test_packages ON package_type.package_type_id = test_packages.test_pack_type_id 
WHERE test_packages.test_pack_id = '21e86b3ebf6a8af2a9fcf136c4f8e88a'

該查詢返回我想要的結果（即package_name）。實際上，我想從上面的數組中爲每個[pack_id]值引發此查詢，並以key =>值格式生成關聯數組，如[pack_id] => 'package_type_name' 我應該如何實現這一目標？任何人都可以幫我解決這個問題嗎？提前致謝。

你可以嘗試這樣的事情嗎？

$arrResult = array(); 

foreach($user_study_test_packages['test'] as $innerArray) 
{ 
    $sql = 'SELECT... WHERE test_packages.test_pack_id = ' . $innerArray['pack_id']; 

    $queryResult = // call you query 

    $arrResult[$innerArray['pack_id']] = $queryResult['package_type_name']; 
}
