Aplus Framework

Aplus Framework.


The installation of this package can be done with Composer:

composer require aplus/framework


This package is responsible for installing other Aplus Framework libraries.

It has the Aplus class, through which it is possible to get information about the current version of the installed framework:

echo Aplus::VERSION;

With this package it is possible to create applications according to the need of the developer.

As examples, you can analyze the App and One projects, which create structures using the MVC library.

Autoloading and Preloading

The framework package contains a file that loads and returns the autoloader with the paths to the defined namespaces, and also a file to preload all the framework classes.

Let's say you want to work with the framework classes defined in just one place in such a way that you can update them all at once.

We assume that the installation is performed via Composer in a directory called composer in your user's home directory.

Create the directory:

mkdir composer

Enter the directory:

cd composer

Use Composer to install the framework files:

composer require aplus/framework

Create a symlink to share the files with all users on the system:

sudo ln -s ~/composer/vendor/aplus /usr/share

With this, you can autoload files from anywhere or preload them, as we'll see next.


Autoload lets you load classes automatically.

To load the framework classes automatically, put this line at the top of your input file (front controller):

require '/usr/share/aplus/framework/autoload.php';

If you want to use the Autoloader instance loaded, pass the require result to a variable:

$autoloader = require '/usr/share/aplus/framework/autoload.php';

If using the MVC library, you can also define this Autoloader instance as a service:

use Framework\MVC\App;

App::setService('autoloader', $autoloader);

Example with Autoloading

Let's see an example autoloading in the index.php file:

use Framework\MVC\App;

$autoloader = require '/usr/share/aplus/framework/autoload.php';
$autoloader->setNamespace('App', __DIR__ . '/app');

App::setService('autoloader', $autoloader);

(new App())->run();

The Autoloader instance was reused, setting the directory to the App namespace and also set as a service in the MVC App class.


Preloading allows loading classes to be available on every request as if they were part of the PHP core.

It makes requests faster and saves memory!

Below we will see how to configure PHP to preload the Framework classes.


In production, it is very common to use FastCGI Process Manager.

The php.ini file of PHP-FPM on Debian-based distributions is located at /etc/php/8.1/fpm/php.ini.

To enable preloading enter the path of the preload file and the username, which is normally www-data:


Then restart the PHP-FPM service:

sudo systemctl restart php8.1-fpm.service

And that's it! Loaded classes. We can use them directly as if they were part of the PHP core!

PHP Server

In development, you can use this package, creating a file called php-server.ini and insert the path to the preload file in the ini section:


And then up the PHP server:


Example with Preloading

With the Framework preloaded, use the classes directly, without needing to autoload or include. Because they are already in memory!

Let's look at a basic file for responding to HTTP requests:

use Framework\MVC\App;

(new App())->runHttp();

And that's it!
