Work in progress..

• Minimum space for the application files: 10 MBytes. Project specific picture files and data require additional space. For a usual project with 500 users, 1 GB should be sufficient.
• PHP, minimum version 5.3.0.
• The PHP configuration option "safe_mode" must have value "off". You might ask your web host provider whether safe_mode is switched off on your server. This option does not exist anymore from PHP version 5.4.0.
• The PHP library GD must be installed. This should be standard at most providers, but you might ask yours anyway.
• The PHP extension JSON must be installed. This should be standard as well.
• MySQL database, minimum version 4.1.
• The MySQL database must support InnoDB. This should be standard, but better ask.
• If using external web services, such as from Facebook and Google+, the PHP extension CURL must be enabled.
• When simulating matches minute-by-minute, it is recommended to have a Cron job which can be executed every minute. Most of the web host providers offer such Cron jobs, however often they often ask an extra charge.
• Your webhost provider should allow the operation of an online game. It is recommended to get a written approval from the provider.
