It really only took a few minutes, once I knew the commands. Tomorrow is simply "+1 day" in the function. It took all day to move my website to a hosting server that offered php5 so I could get it to work.
[edit] I suppose I could have added 86400 seconds to the original time() result as I originally thought, but I like shortcuts like the strtotime (string-to-time) function that lets me speak engrish to the computer.[/edit]
<?php
$lat = 47.3;
$long = -122.1;
$zenith = 90+50/60;
$offset = -8;
echo "<p>Sunrise Today: ".date_sunrise(strtotime(), SUNFUNCS_RET_STRING, $lat, $long, $zenith, $offset);
echo "<br>Sunset Tonight: ".date_sunset(strtotime(), SUNFUNCS_RET_STRING, $lat, $long, $zenith, $offset);
echo "<p><br>Sunrise Tomorrow: ".date_sunrise(strtotime("+1 day"), SUNFUNCS_RET_STRING, $lat, $long, $zenith, $offset);
echo "<br>Sunset Tomorrow: ".date_sunset(strtotime("+1 day"), SUNFUNCS_RET_STRING, $lat, $long, $zenith, $offset);
?>
Result below...
Sunrise Today: 07:53
Sunset Tonight: 16:30
Sunrise Tomorrow: 07:53
Sunset Tomorrow: 16:31
Thanks for the help. Since everything is frozen right now, watching the tickers is kinda boring. A little coding passes the time.
