推荐答案

事实上，您使用数据库在数据库中搜索（相反，它的语言SQL）。 PHP只是将用户输入转换为SQL并将返回的DB数据转换为（可读）HTML。

as a matter of fact, you search in a database by using the database (resp. its language SQL). PHP is only there to transform the user input into SQL and the returned DB data into (readable) HTML.

有任何想法如何使用下拉菜单，组合搜索我的数据库盒子？我真的被困在这里...

have any idea how can i search my database with a use of dropdown menu, combo box?i''m really stuck in here dude..

从头开始搜索数据库是很多代码，你知道吗？并且根据每个部分的外观（至少有HTML，CSS，PHP，SQL（不要忘记数据库布局）和可能的JavaScript），它可以变得非常少。

searching a DB from scratch is a lot of code, you know? and depending on how each part looks (you have at least HTML, CSS, PHP, SQL (not to forget the DB layout) and possibly JavaScript), it can become quite a handful.
