Nemesis is a small PHP Framework that I've started to sustain when I realized I needed a lightweight, native, minimalistic and flexible tool to quickly develop MVC web app or REST api for testing and specific requests which require to work on a basic shared web hosting with few hardware resources.

The architecture is built on well known patterns (Model Controller or Model View Controller) with a basic bootstraper / class autoloader and some procedural functions, so, what PHP can do properly without any extra-dependencies.

The core is customizable according to the components needed and their dependencies

Loader : autoloader

Hook : trigger a hook, depends to Loader

Session : manage a secure session, depends to Loader

Plugin : DEPRECATED

URL : get headers received, hash and output URLs, depends to Loader

Router : create routes, depends to Loader, URL

Api : manage a simple JSON Web Api with a class controller, depends to Loader, URL, Router

MVC : add all components to build a MVC app like a view builder, depends to Loader, Hook, URL, Routes

App : manage a web app built on a MVC pattern with a class controller, depends to Loader, Hook, URL, Routes, MVC

HTMLhelpers : helpers to build html forms, no dependencies

CSSmin : minify CSS, depends to Loader, Hook, MVC

String parser : strip_accents, strip_specialchars, beautify, minimize, excerpt, is_email, is_phone_fr, is_date, datetime, sanitize_output

File manager / Shorcuts : getperms, filename, extension, upload, download

CURL : url_get_contents

key : Key_Generator

• PHP v5.3 or higher installed on your server or web hosting

• htaccess (for Apache) and url_rewriting PHP modules

Nemesis-Framework is now on packagist, so it can be required as a dependency with Composer :

https://packagist.org/packages/kimihub/nemesis-framework

For Apache Servers the content of the .htaccess file located to the server root directory is :

<IfModule mod_rewrite.c>
	#Symlinks maybe needed for URL rewriting
	Options +FollowSymLinks
	RewriteEngine On
	#if you want to exclude some directories from url rewriting
	#RewriteCond %{REQUEST_URI} !^/(site2|site3/.*)$
	RewriteCond %{REQUEST_FILENAME} !-f
	RewriteCond %{REQUEST_FILENAME} !-d
	RewriteRule ^(.*)$ index.php?/$1 [QSA,L]
</IfModule>

And for Lighttpd Servers the content of Lighttpd.conf :

$HTTP["host"]  =~ "www\.mydomain\.com"{
	server.document-root = "/PathToServerRoot/"
	accesslog.filename   = "/PathToLogs/access.log"
 	url.rewrite = (
		"^/(.+)/?$" => "/index.php/$1"
	)
}

Require bootstraper

require_once 'nemesis.php';

To log php errors

get_errors(); // to view errors.log : http://mydomain.com/errors.log

To display php errors

display_errors();

If the core functions are required

core_functions();

If the autoloader is required

core_autoloader();

Router initialization

$loader = Loader::getInstance();
$loader->initClass('Router');

Example of a web app initialization

$blogApp = App::getInstance('blog', '1.0'); // the version is not required
$blogApp->run();
echo $blogApp;
