curir

curir is a zero-configuration web delivery system for PHP applications that is optimized for rapid prototyping.

Installation

To use curir in your own project with Composer, add the following lines to your composer.json.

"require" : {
    "watoki/curir" : "*"
}

To install curir as a stand-alone project you can use

git clone https://github.com/watoki/curir.git
cd curir
php install.php

Quickstart

The easiest way to use curir is to have this one line in a index.php file

WebApplication::quickStart('MyResource');

which packs a request into a Request object, passes it to the given Resource and flushes its Response. The class MyResource could look like

class MyResource extends Resource {
    public function respond(Request $request) {
        return new Response('Hello World');
    }
}

or it could extend DynamicResource which invokes a method corresponding with the METHOD of the HTTP request which can be overwritten with a method query parameter.

class MyResource extends DynamicResource {
    public function doGet() {
        return "Hello World";
    }
}

Routing

There isn't actually much routing going on. All requests are passed to the root Resource provided to WebApplication. Most web applications expose more than one resource though, so the root resource may pass the request to further resources. The Container class for example passes the request to a child based on the requested path. A child resource is simply a class in the folder belonging to a Container. If the container is called RootResource, its folder is called root.

Some routes are dynamic, e.g. posts/42 where 42 might be the post ID. For this purpose, placeholders resources can be used which are resources starting with xx. Also, static resources don't need a corresponding class.

So the file structure of a blog application could look like

web
|- RootResource.php
|- root
  |- PostsResource.php
  |- SearchResource.php
  |- posts
  | |- xxPostResource.php
  |- about.html

The target path is passed as a query parameter, by default - (e.g.http://my.site/blog/index.php?-=posts/42). On Apache, you can use mod_rewrite to send all requests to index.php with

RewriteEngine On
RewriteBase /blog
RewriteRule ^(.*)$ index.php?-=$1 [L,QSA]

Parameters

Query parameters are translated into method arguments by the DynamicResource. So the request my.site/blog/search?text=story&after=2001-01-01 translates to

class SearchResource extends DynamicResource {
    public function doGet(DateTime $after, $text = null) {
        // ...
    }
}

Method arguments can be optional and also provide hints to which type a query parameter should be converted to.
