Atto Servers

Atto is a collection of single file, low dependency, pure PHP servers and routing engines. Currently, Atto has two server classes: WebSite, a pure PHP web server and web routing engine and GopherSite, a pure PHP gopher server and gopher routing engine.

  • Atto Servers can be used to route requests, and hence, serve as a micro framework for use under a traditional servers such as Apache, nginx, or lighttpd.

  • Atto can be used as a standalone server for apps created using its routing facility.

  • Atto is request event-driven, supporting asynchronous I/O for web traffic.

  • Unlike similar PHP software, as a Web or Gopher Server, it instantiates traditional PHP superglobals like $_GET, $_POST, $_REQUEST, $_COOKIE, $_SESSION, $_FILES, etc and endeavors to make it easy to code apps in a rapid PHP style.

As a standalone Server:

  • Atto supports timers for background events.
  • Atto handles sessions in RAM.
  • Atto has File I/O methods fileGetContents and filePutContents which cache files using the Marker algorithm.


require 'atto_server_path/src/Website.php'; //this line needs to be changed

use seekquarry\atto\Website;

$test = new WebSite();
    A Simple Atto WebSite used to display a Hello World landing page.
    After changing the require line above, you can run the example
    by typing:
       php index.php
    and pointing a browser to http://localhost:8080/
$test->get('/', function() {
    <!DOCTYPE html>
    <head><title>Hello World - Atto Server</title></head>
    <h1>Hello World!</h1>
    <div>My first atto server route!</div>

if($test->isCli()) {
       This line is used if the app is run from the command line
       with a line like:
       php index.php
       It causes the server to run on port 8080
} else {
    /* This line is for when site is run under a web server like
       Apache, nginx, lighttpd, etc. The enclosing folder should contain an
       .htaccess file to redirect traffic through this index.php file. So
       redirects need to be on to use this example under a Apache, etc.


Atto Server has been tested on PHP 5.5, PHP 7, and HHVM. HTTPS support does not currently work under HHVM.

To install the software one should have PHP installed. One can then git clone the project or download the ZIP file off of GitHub.

To use Atto Server in your project, add the lines:

require 'atto_server_path/src/Website.php';  //this line needs to be changed

use seekquarry\atto\Website;

to the top of your project file. (GopherSite should be used if you want a gopher server) If you don't have the use line, then to refer to the Website class you would need to add the whole namespace path. For example,

$test = new seekquarry\atto\Website();

If you use composer, you can require Atto Servers using the command:

composer require seekquarry/atto

You should then do composer install or composer update. Requiring "vendor/autoload.php" should then suffice to allow Atto Servers to be autoloaded as needed by your code.

More Examples

The examples folder of this project has a sequence of examples illustrating the main features of the Atto Servers.

Out of paranoia, at the start of each of these examples, there is an exit(); call. This line should be removed or commented to try the example.
