date_sunrise
(PHP 5) date_sunrise --
Returns time of sunrise for a given day and location
Descriptionmixed date_sunrise ( int timestamp [, int format [, float latitude [, float longitude [, float zenith [, float gmt_offset]]]]] ) date_sunrise() returns the sunrise time for a given
day (specified as a timestamp) and location. The
latitude, longitude and
zenith parameters default to the
date.default_latitude,
date.default_longitude and
date.sunrise_zenith configuration options,
respectively.
The latitude defaults to North. So, if you want to
specify a South value, you must pass a negative value. The same note
applies to longitude, which defaults to East.
The gmt_offset parameter is specified in hours.
