int
$date, [int
$retformat = null], [float
$latitude = null], [float
$longitude = null], [float
$zenith = null], [float
$gmt_offset = null], [bool
$sunrise = true])

Calculates sunrise and sunset for a location

The sun position algorithm taken from the 'US Naval Observatory's Almanac for Computers', implemented by Ken Bloom <kekabloom[at]ucdavis[dot]edu> for the zmanim project, converted to C by Moshe Doron <mosdoron[at]netvision[dot]net[dot]il> and finally taken from the PHP5 sources and converted to native PHP as a wrapper.

The date has to be entered as a timestamp!

getWeatherIcon [line 915]

void getWeatherIcon(
string
$condition, [array
$clouds = array()], [float
$wind = 5], [float
$temperature = 70], [float
$latitude = -360], [float
$longitude = -360])

Gets a number corresponding to a weather icon.

These numbers just happen to correspond with the icons that you get with the weather.com SDK, but open versions of them have been created. Input must be in standard units. For the icons that include day/night, we use the present time and the provided lat/lon to determine if the sun is up. A complete set of icon descriptions can be found here: http://sranshaft.wincustomize.com/Articles.aspx?AID=60165&u=0

There are a number of icon sets here: http://www.desktopsidebar.com/forums/index.php?showtopic=2441&st=0 http://www.desktopsidebar.com/forums/index.php?showtopic=819
