现在我想从内部数组发出每个[pack_id]的SQL查询。一个[pack_id]值的演示SQL查询如下：
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'
此查询返回所需的结果（即package_name）。
实际上我想从上面的数组中为每个[pack_id]值触发此查询，并生成一个以key =＆gt;值格式为[pack_id] => 'package_type_name'的关联数组
我该怎么做到这一点？任何人都可以帮我解决这个问题吗？提前致谢。
答案 0 :(得分：1)
你能尝试这样的事吗？
$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'];
}
