在php中读取URL中的变量作为函数

Question

Started learning php this week and had many doubts, but this is one of them which i couldn't find solution(Maybe i didn't know the right keyword to search for).

Is it possible to read variables in URL as a function inside a php file, for example :

  http://mywebsite.com/demo_app/phone_api/login/harsha/harshapass

Here demo_app is the folder, phone_api is the php file, and i want to invoke the function login, where harsha and harshapass is the paramaters to that function.

Answer 1

You'll need 2 things for this.

The first is mod_rewrite, this is an apache module. With this module you can rewrite the URL like you want, so that /demo_app/phone_api/ will redirect to your php file.

I advice that you read a tutorial somewhere about this, for example here.

Second thing is that you need to parse the URL.

With $_SERVER['REQUEST_URI'] you get the URL. With explode and/or preg_match you can parse this string into the parts you want (function, parameters, whatever).

If you have a more specific question about this, you can ask this here (in a new topic).

Good luck!
