LibAPCNIS is a PHP library for accessing the NIS port of the Apcupsd UPS Monitoring daemon. This library allows you to access realtime UPS stats right from a PHP script without the need for having Apcupsd installed on the server that the script is being executed on. This library does NOT require the apcaccess application that is included with an Apcupsd installation. There are no external dependencies because only built-in PHP functions are used to query the information.
