Requirements
Domain portfolio manager has been created with as much effort as possible in making sure that the script works on as many servers as possible. As with many scripts however there are a few requirements. The current requirements currently consist of the following:
PHP 5.2 (or greater)
Domain Portfolio Manager uses certain functionality of PHP that was only introduced in PHP 5.2. If you have a version prior to this version I urge you to encourage your host to update PHP.
mySQL 4.3 (preferably 5 or greater)
Domain Portfolio Manager uses certain functionality that enhances the script. Therefore version 4.3 or greater is encouraged. Ideally version 5.x should be used.
cURL
cURL is currently used for getting information from 3rd party websites. Addon's also use this method.
Allow url fopen
Allow url fopen is a configuration option within PHP itself. This directive stops certain functions within PHP from accessing external sites. Although this can increase security it can restrict PHP functionality. Domain Portfolio Manager makes use of this directive for retrieving updated whois information as well as retrieving the relevant whois servers. If this setting has been disabled your domains whois will not be retrieved automatically.
Optional
Domain Portfolio Manager also has the following optional requirements. Although they are not critical they can help the script run more efficiently:
Cron
Domain Portfolio Manager does not require true cron as it has a pseudo cron functionality however true cron can ensure that regular tasks are indeed carried out when needed. For more information about the advantages and disadvantages of pseudo cron please see HERE.
