Php MYSQL使用循环填充数据

我是mysql的初学者

我有一个任务。有三张桌子

购买\u母版

"autoid","user_id","package_id"

"autoid","user_id","name","user_email","user_pass"

"poster_path","overview","release_date","genre_ids","package_id","original_title"

用户\u主机

"autoid","user_id","package_id"

"autoid","user_id","name","user_email","user_pass"

"poster_path","overview","release_date","genre_ids","package_id","original_title"

主程序包

"autoid","user_id","package_id"

"autoid","user_id","name","user_email","user_pass"

"poster_path","overview","release_date","genre_ids","package_id","original_title"

我的要求是，应该填充purchase_master表，以便它包含来自

package_master

的所有包，而不是来自

user_master

的每个用户

e、 例如，如果

user\u master

中有10个用户，而

package\u master

中有10个包，那么

purchase\u master

将有100行（10个用户*10个包）。所以每个用户都有10个包

我不知道如何在mysql中做到这一点，否则我必须找到一种通过循环在PHP中做到这一点的方法

试试这样的东西

INSERT INTO purchase_master ("user_id","package_id")
  SELECT um."user_id", pm."package_id"
  FROM user_master as um
  JOIN package_master as pm

希望这有帮助

文档：

获取用户和软件包的所有数据。。然后使用phpFetch循环它以填充数据从两个表中提取所有数据，并使用

foreach

填充您的

purchase\u master

表。
