Introduction

Program O is an AIML interpreter written in PHP, and uses a MySQL database to store chatbot information, including the AIML files used to formulate the chatbot's responses.

System Requirements

Program O requires PHP version 5.4.0 or higher to function. It also requires the following PHP extensions:

• PDO (as well as at least one PDO driver - the MySQL driver is recommended for most users)
• cURL
• mbString
• Zip

Configuration

Program O supports the creation of multiple chatbots. The individual bots are configured from the admin area. Bot specific settings and variables are stored in the database. Configuration of Program O itself is stored in /config/global_config.php.

Using the bot

After installation you can chat with your Program O chatbot using several methods:

• Through a static HTML page (example in /gui/plain/index.php)
• Through an AJAX enabled web page (example in /gui/jquery/index.php)
• Through the Program O API (example in /gui/xml/index.php)

For advanced botmasters and programmers, it is possible to use the Program O API to access a chatbot from stand-alone applications through HTTP requests. for information on how to create and/or use such a stand-alone application, please visit the Program O website.

Foreign Language Support

v2.2 and higher now supports Unicode characters, allowing chatbots to be created that use non-English languages, such as Arabic, Chinese, French, Greek, Russian, Turkish, Thai, and many others.

Upgrade

Upgrading from version 1 to version 2 is no longer supported. If you want to "upgrade" your chatbot from version 1 to version 2, you will need to save your AIML files from the current chatbot, perform a "clean install" of Program O, and then upload the AIML files to the new installation. With the release of Program O version 2.2, the differences in structure and functionality between version 1 and version 2 became too great to continue supporting the transition.

Clean install

Starting with version 2.0.1 and later, there is an automatic installer provided for clean installation. Simply point your web browser to your freshly uploaded Program O directory to run the install script. Then follow the instructions on the page. The installer is designed to only run once.

Please note that the installer script will NOT create your database for you, nor will it install your bot's AIML files. The database, along with the username/password used to access it, needs to be created in advance. See the file fresh_install_README.txt for more information.

After you create the database, and once you complete the installation process, simply go to your new Program O admin page (e.g. http://www.example.com/ProgramO/admin) and log in using the admin credentials you provided during the install process. Then select "Upload AIML" from the navigation link on the left and upload your AIML files. Then sit back and enjoy your new bot!
