calculateMoonPhase [line 823]

PEAR_Error|array calculateMoonPhase(
int
$date)

Calculates the moon age and phase

The algorithms for this functions were taken from the German Wikipedia entry on Julian Daycount for getting the accurate JD to the second and the overall moon calculation were done according to Stephen R. Schmitt's website, which is cited multiple times on the web for this kind of calculation.

The date has to be entered as a timestamp!

getWeatherIcon [line 1181]

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

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
