Using PHP Weather is very simple. First you have to include the
file phpweather.inc in your page. Then you call the
function get_metar() with the four-character
station-identifier. This gives you the METAR, which you can then feed
to process_metar(). This function return an array that
contains the various parts of the METAR in decoded form. They are also
returned in both imperial (feet, miles, degrees of Fahrenheit, etc.)
and metric SI units (meters, kilometers and degrees Celsius).
This code is all that is necessary to make PHP Weather work:
<?php
include('phpweather.inc');
include('locale_en.inc');
$metar = get_metar('EKYT');
$data = process_metar($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>";
?>
That's it! The above code will tell you what the temperature is in Aalborg, Denmark:
The temperature is degrees Celsius ( degrees Fahrenheit).
But you'll probably want the nice large examples you saw on the
previous pages? To make the examples above I've made a function called
pretty_print_metar(). You use it like this:
<?php
$metar = get_metar('EKYT');
include('locale_en.inc');
pretty_print_metar($metar, 'Aalborg, Denmark');
?>
This will give you an English text with the current weather in Aalborg, Denmark:
Sorry! There is no data available for Aalborg, Denmark.
