mysql - Accessing database content based on /variable

Question

So I am a bit new to MYSQL and I've been learning allot more about relational databases but I am a bit stumped with one subject in mind. I notice allot of sites have things like domain.tld/variable. I understand how this works by using /?variable=name but most users would never use that. So how does one go about letting users pull content based on the principal listed?

Answer 1

实际上，这与数据库无关。

访问url时，使用url重写，在后台改变url。当用户输入domain.com/data时，会打开 php 脚本（或其他任何东西）domain.com?variable=data。
