Installation

ANN - Artificial Neural Network for PHP

This chapter describes the steps to implement the ANN source code to your project.

Documentation

• Documentation (HTML online)

Requirements

The latest implementation requires a php environment running PHP 5.4.x or above. If using the client-server mechanism of the network class, the curl extension should be available on the client host which connects to an ANN server. If using class ANN_NetworkGraph GD library with png support should be installed.

Installation

• Download the source code

• Checking integrity

>md5sum ann230*

• Unpack the source code

>tar -xzf ann230.tar.gz

• Copy the directory ANN to your library directory of your project.

• Including to your source

<?php

require_once 'ANN/Loader.php';

use ANN\Network;

$objNetwork = new Network;

or as phar library (supported as of PHP 5.3.0)

<?php

require_once 'phar://ann230.phar.gz';

use ANN\Network;

$objNetwork = new Network;

• Learn to use the library. Have a look to chapter Examples.

• For further information e.g. about dat-files have a view to the FAQ page.

Performance issues

• Install Zend Optimizer (PHP version before 5.3.0)
• Do not use any debugger module like xdebug
• Do not use any profiling tool
• Do not set "max_execution_time = 0" in your php.ini or .htaccess file
• Running PHP on Linux console use "php -d max_execution_time=60 neural.php"
• Run implicit ini_set() call to set "max_execution_time" by runtime
• Use PHP 5.3.x
• Use PHP 5.4.x (much faster than PHP 5.3.x)
