现在我想[pack_id]从内部数组中为每个触发一个 SQL 查询。一个单个值的演示 SQL 查询[pack_id]如下所示：
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'
此查询返回我想要的结果（即 package_name）。实际上，我想为上述数组中的每个[pack_id]值触发此查询，并以 key=>value 格式生成一个关联数组，[pack_id] => 'package_type_name'
我应该如何实现这一点？谁能帮我解决这个问题？提前致谢。
