PHP File-based routing

This is my unstable version of file-based routing, inspired by Javascript Libraries/Frameworks, to make my project's URL tiny-little-bit-beautiful even my backend is an instant legacy code.

Sooo @frozeeen, again what's this?

Well, here you go

https://yourawesome.web/post?id=ABCDEFG12345
to
https://yourawesome.web/post/ABCDEFG12345

Installation

1. Simply clone this project into your machine.
2. Update the config inside the index.php.
3. and presto! all set.

Structure

The structure is very simple

pages # This is where your pages will live
assets # Maybe some of your CSS, JS and other assets
index.php # And this is where some tiny-little-bit magic polynomial time happens, it's the router
.htaccess # We don't talk about .htaccess -Dani

How to use this?

To use this, let's head into pages folder and make some files.

Static routing

Path: pages/your-awesome-page.php
URL: http://website.com/your-awesome-page

Dynamic routing

To create a dynamic url like https://website.com/post?id=YOURPOSTID we're going to do it like this.

# Create a file
Path: pages/post/[id].get.php

# To access
URL: https://website.com/post/YOURPOSTID

and to access the id inside our code, it's just like normal $_GET, the name between the brackets [] is the parameter or key (they call this slug).

Showing post ID: <?php echo $_GET['id']; ?>

Nested Dynamic routing

We can also create a folder to become our slug.

Path: pages/post/[id]/edit.get.php
URL: pages/post/YOURPOSTID/edit

So the file structure will look like this and let's add some additional files.

pages/
  post/
    [id]/
      index.get.php
      index.delete.php
      edit.get.php

The following endpoints correspond to the files in the structure above:

GET    /post/123
DELETE /post/123
GET    /post/123/edit

Request method per file

This is heavily inspired by the Nitro for mapping the request method per file.

Each file is prefixed with the request method and has a .php file extension. For example, if we are creating CRUD functionality, the structure would look like this:

[id]/
  index.get.php
  index.post.php
  index.put.php
  index.delete.php

Middleware

Yet another very simple middleware.

Middleware is a script that runs before the page script is loaded; it can be used to check authentication or execute high-level intergalactic computations prior to producing the page.

To create a middleware, create a file named +middleware.php.

pages/
--auth/
----+middleware.php
----profile.get.php
----index.get.php

In the file structure above when we try to access /auth/profile or any page inside the /auth folder, it will first run the +middleware.php script.

In addition, if a given user is not authorized to visit a specific endpoint, you can do $is_not_found = true inside your middleware.php to send a 404 error.

$is_not_found variable is a (page exist) flag inside the index.php
