Re: Using PHPWeather question

[Daisyhead <je...@da...>]

Okay, so what if I just want a simple list of certain things? This is the
code I have, but the only things pulling info are the temp, wind and
humidity fields. Can I do something like below and still have it pull all
the info I want?

<?php
require('/home/xxx/public_html/weather/phpweather.php');
$weather = new phpweather();
$weather->set_icao("KOMA");

$foo = $weather->decode_metar();

$temp_c = $foo['temperature']['temp_c'];
$temp_f = $foo['temperature']['temp_f'];
$miles_per_hour = $foo['wind']['miles_per_hour'];
$dew_point = $foo['dew-point']['dew_point'];
$visibility_less_than = $foo['visibility']['visibility_less_than'];
$feelslike = $foo['feelslike']['feelslike'];
$weather = $foo['weather']['weather'];
$rel_humidity = $foo['rel_humidity']['rel_humidity'];
$altimeter = $foo['altimeter']['altimeter'];

echo "Temp: $temp_f &deg; Fahrenheit<br>";
echo "Feels like: $feelslike<br>";
echo "Conditions: $weather<br>";
echo "Wind: $miles_per_hour MPH<br>";
echo "Humidity: $rel_humidity %<br>";
echo "Dewpoint: $dew_point<br>";
echo "Pressure: $altimeter<br>";
echo "Visibility: $visibility_less_than";
?>

If you want a "shortcut" you should use the methods in
output/pw_text.php.  It has methods like print_pretty(),
print_pretty_visibility(), print_pretty_clouds().  It will even be in
the language you set.  Look at the index.php file, it has all the
necessary steps.  For your needs, I would put in
print_pretty_visibility() and not print_pretty(), which is what the main
page of phpweather uses.

Thank you Martin. I guess it's just because I'm not all that familiar with
PHP yet. I am looking at the documentation that came with my v2.x download
and I've managed to figure out how to call in the temp and wind speed, but
am having problems with things like visibility and cloud cover, etc. Is
there any way to use a "shortcut" and call in all the variables?

I wouldn't do that unless either i) you are the only user on your server, or
ii) PHP is in safe mode. Otherwise, some other user could include() your
file, and retrieve your password.

That's the one!

mmm, odd - I'm fairly sure it's the same params (no other db/user/pass 
is valid) and yet I'm seeing that 1 page refresh shows Connections 
Counter+2 under MySQL CC. There's only my 'insert a pageview' thingy 
which assumes an open connection (ie it's opened by the main page 
script) and then there's my call to phpWeather - nothing else talks to 
the database.

I guess I need to do more hunting.

If you're worried about having two open links to MySQL at the same
time, then there's no problem, the PHP manual says:

  If a second call is made to mysql_connect() with the same arguments,
  no new link will be established, but instead, the link identifier of
  the already opened link will be returned.

If you're annoyed about having your password spread across several
files, then the easiest solution is to make your defaults.php file
reference the password as a variable:

  /* db_password */
  $this->properties['db_password'] = $GLOBALS['password'];

and then make sure that $password is in the global scope.

And finally, there is a disconnect method in all the database
backends, but it isn't used at the moment, and I don't think that will
change, it's just there for completeness.

The code you're trying to use was written for the obsolete 1.x series
of PHP Weather.  Unless you have a really old installation of PHP, or
some other strange demands, then you should use the new 2.x series,
specifically version 2.2.1:

The 2.x series have better (but still far from perfect) documentation,
which you'll find in the tarball/zipfile.

If you're using pconnect() - permenent connections to the database, it
doesn't matter - it'll just use an existing connection if one is open.

Re: Using PHPWeather question

[Daisyhead <je...@da...>]

Max,

Could I ask one more question? I'm trying to add other tags and my current
code looks like this:

<?php
require('/home/xxx/public_html/weather/phpweather.php');
$weather = new phpweather();
$weather->set_icao("KOMA");

$foo = $weather->decode_metar();

$temp_c = $foo['temperature']['temp_c'];
$temp_f = $foo['temperature']['temp_f'];
$miles_per_hour = $foo['wind']['miles_per_hour'];

echo "Temp: $temp_f &deg; Fahrenheit<br>";
?>
echo "Wind: $miles_per_hour MPH";
?>

But I cannot get the wind speed to show up. Any idea what I'm doing wrong? I
thought you could just plug in the other tags you want and Presto!

Thanks,
Jenni

I totally understand Max. I apologize if I came off as being pushy and/or
rude. I was just frustrated by not being able to get it running. I wish
there was a forum or something so we could get a little more help. Although
I suppose the product was written for people with more knowledge of PHP and
SQL than myself.

Thanks again!

RE: Using PHPWeather question

[Max H. <ma...@fl...>]

Jenni,

almost there.

<?php
require('phpweather.php');
$weather = new phpweather();
$weather->set_icao("KOMA");

$foo = $weather->decode_metar();

$temp_c = $foo['temperature']['temp_c'];
$temp_f = $foo['temperature']['temp_f'];

echo "<p>The temperature is $temp_c degrees Celsius ($temp_f degrees
Fahrenheit).</p>";
?>

If this script isn't in the same place as the phpweather install, you'll
need to modify the first line accordingly.

Incidentally, we're all busy people doing other things, so don't be suprised
if a reply takes a day or two.

Cheers,

Max

phpWeather Feature Request

[Phil P. <phi...@sw...>]

 From what I can tell, once you configure phpWeather to talk to MySQL, 
it will make its own connection to the database.

I've added data from phpWeather to my webpage, and it's all working fine.

However in the process of generating my page, I already initiate a 
connection to the database.

Is there any *really simple* way I can pass these details to phpWeather 
for it to use? Assuming, of course, that phpWeather won't blithely go 
and close the pre-existing connection once it's done with it.

Thanks,
Phil P

Using PHPWeather question

[Jenni <je...@da...>]

I have installed and configured PHPWeather, but am having problems actually
getting it to work on my blog. I am fairly new to PHP and MySQL, although
I've been able to teach myself enough to figure most things out. But for
some reason I cannot figure out how to call the weather information into my
blog. I tried using:

<?php
include('phpweather.inc');
include('locale_en.inc');
$metar  = get_metar('KOMA');
$data   = process_metar($metar);
$temp_c = $data['temp_c'];
$temp_f = $data['temp_f'];
echo "<p>The temperature is $temp_c degrees Celsius ($temp_f degrees
Fahrenheit).</p>";
?>

I cannot see where I have a filed named "phpweather.inc" or "locale_en.inc"
Can anyone clue me in as to what I did wrong? The documentation isn't very
user friendly for us newbies.  ;-)

Thanks,
Jenni

     // $metar_time = $date[0].$date[1].$date[2].$date[3].$date[4]."00";

and shortly after calls to both insert_metar() and update_metar() *but 
with only 3 parameters* as opposed to 4 as per the function definitions.

So I uncommented the $metar_time assignment, and appended
	,$metar_time
as the 4th parameter to the insert/update metar calls.

Much Better.

Enjoy,

I'm afraid I don't understand fully your problem.  The data is not the
latest, as in a few hours old?  Unfortunately the data from noaa is
sometimes a bit late.  Especially in Canada, sometimes the reports are
2-3 hours old.

There should be no problem with that.  Again, by refresh what do you
mean?  Having the page refresh automatically every x minutes?

If you are using the same methods as in the main page (index.php) you
should get the latest data.  Again it might not be the most recent data,
but the most recent AVAILABLE from noaa.


If you want to see if the data displayed in the web page is the same
that is available, point your browser to 

http://weather.noaa.gov/pub/data/observations/metar/stations/$icao.TXT

where $icao (upper case) is the icao code of the station.


Also, make sure you are using the latest version of phpweather (2.2.1).


cheers,
Etienne

Summary: UK language file - meter/metre

Initial Comment:
I have done a UK English language file, since we spell 
metric units differently:

metres
kilometres

rather than the American

meters
kilometers

Don't know where to submit the file to though.

Re: pw_images, UTC, TimeZones, LocalTime

[Phil P. <phi...@sw...>]

Here are some of my random thoughts on enabling sunrise/sunset 
calculations in PHP Weather.

Current entries in pw_stations = 5130
Entries from NOAA (http://weather.noaa.gov/data/nsd_cccc.txt) = 6486

- Read the NOAA datafile and update pw_stations
	- additional fields for LAT and LONG, STATE, ALTITUDE
	- add records for new STATIONS (1356 new entries)

Goal: finding current 'offset from UTC including Daylight Savings if 
required' for a station

Source: the Public Domain TimeZone Database
(http://www.twinsun.com/tz/tz-link.htm)

As well as being a database of all the timezones
	including their DST usage
	zone.tab lists (amongst other things)
		ISO 3166 2-character country code
		TimeZone used
			
So, we can match a CC from our stations list to an entry from zone.tab
(for speed put the TimeZone into a field in pw_stations)

This tells us which timezone to use.
In theory, getting the total offset from GMT should then be as simple as
	$realTZ = getenv('TZ');
	putenv ("TZ=$timeZone");
	$GMT_offset = date('O');
	putenv("TZ=$realTZ");
				
.... Now we have
	ICAO
	Name
	ISO CC
	Country Name
	State
	Latitude
	Longitude
	current GMT offset including DST
	
Grab PHP example code from http://www.zend.com/codex.php?id=135&single=1

I ran a check with co-ords for Sydney, given a hard-coded $DST=1
	this code produces data correct to within 10 minutes
	ie good enough for our uses
	
- tweak code
- not calculate DST , just needs $GMT_offset_including_DST
- accept co-ordinates as either DMS or decimal
	(ie auto-convert DMS to decimal)
- input params
	( GMT DATE,  lat, long , local GMT offset including DST )
- returns list($sunriseTimeStamp, $sunsetTimeStamp)
	
- hack code in pw_images.php
	to identify night_or_day via these calculations

Thoughts/comments/suggestions?
