Re: PHP Weather 2.1.2

[Dan M. <da...@da...>]

I have figured out after struggling a bit how to pull most of the 
information in 2.1.2, but I am still having difficulties pulling 
"Clouds" and "Weather." I know that the information is in an array, but 
I am unclear on how to bring it out of the array.

I also cannot seem to pull wind direction (SW, NW, W), but I can pull 
the compass degree (135, 90, 110).


Here is the code:


$weather = new phpweather();
$icons   = new pw_images($weather);
$location = $weather->get_location();
$image   = $icons->get_sky_image();
$data = $weather->decode_metar();
$temp = $data[temperature];
$windvar = $data[wind];             <-----This Doesn't Work
$cloudvar = $data[clouds];            <-----This Doesn't Work
$time =  date("m/d/y g:i a",($data[time]));
$weathervar = $data[weather];


  echo "\n";
echo "<div align='center'>
Portland, Oregon<br />
<img src=\"$image\" height='45' width='75' border='0' alt='Current Sky' />";


echo "<br />$weathervar[condition]<br />

</div>";

echo "<b>Temperature:</b> $temp[temp_f]&deg;F<br />";
echo "<b>Humidity:</b> $data[rel_humidity]%<br />";
echo "<b>Wind:</b> $windvar[miles_per_hour]mph<br />
<div align='center'>$time</div>
";

Thank you,

Hey Dan,

I had a problem where the METAR info that is pulled from the site and
imported into the database went stale and wouldn't refresh. Anyone have
the same issue? Maybe I didn't configure it right, but I do remember setting
a timeout or expiration time.

I had this same issue when I was playing with 2.1.2. What I actually
printed all the values in the array and see what info I could sort out and
pull, but I couldn't find wind info.

I'm going to play with 2.1.2 now and see what I can do with it.

First of all, please remember to use strings when you index into an
array. Like this: $var = $some_array['some index']. The other way is
deprecated...

To see the structure of the array do this:

  echo "<pre>\n";
  print_r($data);
  echo "</pre>\n";

Then you'll see that $data['wind'] is yet another array that contains
up to eight entries depending on the weather. You'll always find these
entries:

  $data['wind']['deg'];               // Wind direction in degrees
  $data['wind']['knots'];             // Wind speed, knots.
  $data['wind']['miles_per_hour'];    // Wind speed, miles per hour.
  $data['wind']['meters_per_second']; // Wind speed, m/s.

If there are gusts, then you'll find these entries as well:

  $data['wind']['gust_knots']
  $data['wind']['gust_meters_per_second']
  $data['wind']['gust_miles_per_hour']

Finally, the wind might be varying between two directions:

  $data['wind']['var_beg']
  $data['wind']['var_end']

As for the $data['clouds'] entry, then this is an array of arrays. The
first entry is the first cloud-layer, the second entry is the layer
above etc. So

  $data['clouds'][0]['condition']

could be FEW if there were few clouds in the first layer. The altitude
of this layer is

  $data['clouds'][0]['metar']  or
  $data['clouds'][0]['ft'].

The second layer (if there is such a layer) is stored at
$data['clouds'][1].

You'll notice that the data in $data is language-neutral. You'll have
to provide your own strings for N, NW, W etc when you parse the
data. The best way would probably be to make a new method in
pw_text.php and then reuse the strings and other methods that are
already present there.

If you come up with a good extenstion of pw_text.php, then please send
it to the list so that it can become part of the distribution.
