Lean Framework PHP

Lean Framework is a tiny PHP framework (~40KB), modern frameworks are powerfull but so much complicated. With Lean I can construct apps really fast, using mvc, namespaces, autoloader, routes and more.

Requirement

PHP 5.3+

Basic structure

-- app
	-- main (module)
		-- controllers
			-- BasicController.php
		-- models
		-- views
			-- basic
				-- index.phtml
	-- secondary (other module)
		-- controllers
		-- models
		-- views
-- public_html
	-- css
	-- js
	-- img
	-- index.php
	-- .htaccess
-- settings
	-- Bootstrap.php
	-- Routes.php
-- vendor
	-- Lean
	-- autoloader.php

Easy configuration

create file index.php into public_html

<?php require_once '../settings/Bootstrap.php'; ?>

create file .htaccess into public_html to custom urls

RewriteEngine On
RewriteCond %{REQUEST_FILENAME} -s [OR]
RewriteCond %{REQUEST_FILENAME} -l [OR]
RewriteCond %{REQUEST_FILENAME} -d
RewriteRule ^.*$ - [NC,L]
RewriteRule ^.*$ index.php [NC,L]

create file autoloader.php into vendor directory, and use the Symfony Autoloader

<?php

require_once __DIR__ . '/Lean/Libs/Symfony/Component/ClassLoader/UniversalClassLoader.php';

/*
 * add new libs in autoloader is easy, clone libs in vendor directory and add array position, see example to Zend Framework and Amazon Web Service libs
 * $loader->registerNamespaces(array(
 * 		'Lean'     => __DIR__,
 *		'Zend'     => __DIR__,
 * 		'AWS'     => __DIR__
 * ));
 *
 * Just for now add only Lean Framework PHP lib, see below
 */
$loader = new Symfony\Component\ClassLoader\UniversalClassLoader();
$loader->registerNamespaces(array(
	'Lean'     => __DIR__
));

$loader->useIncludePath(true);
$loader->register();

create file Bootstrap.php into settings

<?php
require_once '../vendor/autoloader.php';


/
 * errors
 */
error_reporting(E_ALL);


/
 * include path
 */
set_include_path(
	PATH_SEPARATOR . '..' . DIRECTORY_SEPARATOR . 
	PATH_SEPARATOR . get_include_path());


/ 
 * locale e zone 
 */
date_default_timezone_set('America/Sao_Paulo');
setlocale(LC_ALL, 'pt_BR', 'pt_BR.iso-8859-1', 'pt_BR.utf-8', 'portuguese');


/
 * init lean framework
 */
Lean\Launch::instance()->run();

Create a controller

It's work, access in your browser http://localhost/lean_project/public_html

Remember, in your domain shows only www.yourdomain.com

<?php
namespace app\main\controllers;

class IndexController extends \Lean\App
{
	public function index()
	{		
		echo 'HELLO WORLD';
	}
}

Call non-default module, controller and method, type in your browser localhost http://localhost/lean_project/public_html/foo/product/do-something

Remember, in your domain shows only www.yourdomain.com/foo/product/do-something

<?php
namespace app\foo\controllers;

class ProductController extends \Lean\App
{
	public function do_something()
	{		
		/*
		 * your action here
		 */
	}
}

Using REQUEST object into controller

http://localhost/lean_project/public_html/foo/product?name=foo&category=bar&price=15

<?php
namespace app\foo\controllers;

class ProductController extends \Lean\App
{
	public function index()
	{		
		/
		 * get HTTP $_REQUEST
		 */
		$request = $this->request();
		$name = $request->name;
		$category = $request->category;
		$price = $request->price;
	
	
		/
		 * get only $_POST
		 */
		$request = $this->request()->post();		

		
		/
		 * get only $_GET
		 */
		$request = $this->request()->get();		

		
		/
		 * get only $_FILE
		 */		 
		 $request = $this->request()->file();		
		 
		 
		/*
		 * your action here
		 */
	}
}

Using Views

Create followings views index.phtml and edit.phtml into views

-- app
	-- foo (module)
		-- controllers
			-- ProductController.php
		-- models
		-- views
			-- product
				-- index.phtml
				-- edit.phtml
			-- layout
				-- header.phtml
				-- footer.phtml
				-- template.html

Create template.phtml in layout directory, you can include header and footer parts here

<html>
<head>
	<title>My new app</title>
</head>
<body>

	<? $this->app->view->render('layout.header') ?>

	<div id="container">
		<!--
		-- content page setted in controller will be render here
		-->
		<? $this->app->view->make('content') ?>
	</div>
	
	<? $this->app->view->render('layout.footer') ?>
	
</body>
</html>

Controllers shows yours views

<?php
namespace app\foo\controllers;

class ProductController extends \Lean\App
{
	public function index()
	{	
		/
		 * set the product/index.phtml to be render
		 */
		$this->view()->set('content', 'index');
		
		/*
		 * render the template
		 */
		$this->view()->render('layout.template');
	}
	
	public function edit()
	{	
		/
		 * this render file "../views/product/edit.phtml"
		 */
		$this->view()->set('content', 'edit');
		
		$this->view()->render('layout.template');
	}
}

Using routes

add into Bootstrap.php before launch Lean

...

/
 * routes
 */
Lean\Route::set_routes_path('settings/Routes.php');

/
 * init lean framework
 */
Lean\Launch::instance()->run();

Basic route

create file Routes.php into settings

<?php
use Lean\Route;

Route::set('foo/bar', function() {
	echo 'Hi';
});

Route to method in controller

<?php
use Lean\Route;

Route::set('product/do', array(
	'module' => 'basic', 
	'controller' => 'product',
	'method' => 'do_something'
));

Route to method in controller, same result as above but with clousure and call controller manually

<?php
use Lean\Route;

Route::set('product/do', function() {
	new app/basic/controllers/ProductController::singleton->do_something();
});

Simple alias

Route::alias('do-something', 'product/do');

Multiple alias

Route::alias(array('do-something', 'do-something2', 'foo', 'bar'), 'product/do');
