Any help is appreciated

Night Time Images

[Jake O. <ja...@or...>]

This is probably a fairly stupid question that hopefully has a simple fix.

I'm running a version of 2.0 on my site (I think it's a pre-2.0 final CVS
release, so if it's been fixed in the final release, let me know). It
provides the simple current weather for the area for our rental guests
(http://www.sunrayinc.com/sunriver/weather/) using a modified print_table
function. However, as you'll see right now, it's showing a nighttime
part-cloud graphic, even though it's only 4:30 here right now. I tried
setting the time offset before, and it didn't work (or maybe I didn't set it
right?). Any body have any ideas?

With PHP Weather there's no such thing as a stupid question - new
problems surface regularly... :-)

There has not been a release of the 2.0 code yet, although it's the
code that I'm using at gimpster.com and at phpweather.net...

No, it's not your fault - it's a problem in pw_images.php at line 266:

      } elseif (ereg('([0-9]{2})([0-9]{2})([0-9]{2})Z', $part, $regs)) {
        if (($regs[2] < 6) || ($regs[2] > 18)) {
          $night = 1;
        }

The regular expression matches the date-part of the METAR and the
if-statement in the next line tries to figure out if it's night or
day... The problem is, that this is calculated using UTC time: a
report made at 16:30 PDT in Oregon (the afternoon) is made at 23:30
UTC which is night-time according to the if-statement above.

Yes, change the test so that it's correct for your timezone. Use

        if (($regs[2] > 1) && ($regs[2] < 13)) {
          $night = 1;
        }

instead - that should be correct for the Pacific Time Zone.

This could probably be automated using date('Z')...

That didn't work. It's 11:30 am pacific time right now, and there's a moon
graphic on the site :-).

Hmm, that's odd. Let me try and explain how I came up with '> 1' and
'< 13'. The Pacific Time Zone is UTC - 7 hours because of Daylight
Saving Time, correct me if I'm wrong, I've got my information from
this page:

  http://www.timetemperature.com/tzus/oregon_time_zone.shtml

So a timeline would look like this:

 PDT: 00 ~~~~~~ 06 ------ 12 ------ 18 ~~~~~~ 24

where the ~ marks the hours that belong to the night. The
corresponding UTC timezone is:

 UTC: 07 ~~~~~~ 13 ------ 19 ------ 01 ~~~~~~ 07

So, this means that it's night at your place when the hour is between
7 and 13 UTC or 1 and 7 UTC, i.e., from 1 to 13 UTC. So unless someone
can find an error in the above calculations, then I cannot understand
why it doesn't work for you...

Ups - the docs are outdated...

This should give you the report:

<?php
require('phpweather.php');
require('output/pw_text_en.php');
require('output/pw_images.php');

$weather = new phpweather(array('icao' => 'KLAX'));
$text    = new pw_text_en($weather);
$icons   = new pw_images($weather);

echo $text->print_pretty() . "<br />\n";
echo '<img src="'.$icons->get_sky_image().'" />';
echo '<img src="'.$icons->get_winddir_image().'" />';
echo '<img src="'.$icons->get_temp_image().'" />';

?>
