I have to create an automatic weather including rain, snow, clouds, fog and sunny.
Depending on the season I need to set a percentage for all weather: the forecast will be updated 3 or 4 times during a day.
Example: Winter | Rain: 30% Snow: 30% Sunny: 10% Cloudy: 10%, Fog: 20%
I do not know how to implement a random condition based on percentages. Some help?
Many thanks and sorry for my bad English.
Well, you can use:
$location = 'Rome';
$document = file_get_contents(str_replace(" ", "+", "http://api.wunderground.com/auto/wui/geo/WXCurrentObXML/index.xml?query=".$location));
$xml = new SimpleXMLElement($document);
echo "$location: ".$xml->temp_c."° C";
Just take a look on the XML and see what data you have available.
EDIT
I didn't understand what the OP wanted the first time. Basically, it's even easier.
$weather = mt_rand(0,100);
$season = 'winter';
switch($season) {
case 'winter': {
if ($weather < 30) {
$output = 'Rainy';
} else if ($weather >=30 && $weather < 60) {
$output = 'Snowy';
}
// goes on on the same ideea of testing the value of $weather
break;
}
// other seasons
}
echo $output;
What I suggest tough, is to keep your values in arrays (for example the seasons) as well as the values for chances to have one type of weather or another.
array (
[winter] => array (
[30] => 'Rainy',
[60] => 'Snowy',
... // the other chances of weather
),
[spring] => array (
...
),
... // and so on
)
Use mt_rand(0,100) to get a random value and the array above to determine the weather.
Please let me know if this works for you.
Great answer by Claudiu but if you want to view with Fahrenheit (F) that possible example Below:
<?php
$location = 'Washington';
$document = file_get_contents(str_replace(" ", "+", "http://api.wunderground.com/auto/wui/geo/WXCurrentObXML/index.xml?query=" . $location));
$xml = new SimpleXMLElement($document);
echo $xml->temp_f . "° F";
?>
