yr.no PHP库

yr.no挪威气象服务的PHP库。目前在挪威一个相当大的网站上使用。

状态

请注意，我现在没有添加更多功能（除了接受pull请求）。考虑使用forecast.io之类的工具，它有更多数据。

要求

PHP 5.3

安装

使用 composer

composer require eigan/yr

不使用composer

克隆，或者以zip格式下载仓库。将其放置在服务器上的某个位置。然后在代码中包含autoload.php文件。

请记住在php.ini中设置 date.timezone = "Europe/Oslo" 或您的时区。

变更日志

2014年3月9日

! Yr::create() 现在返回一个Location对象
! 移除了getLocation，使用getName()、getCountry()、getType()代替
! 当指定null作为参数时，预报方法将不再返回数组。请尝试使用toArray()代替
添加autoload.php，使其在结构更改时更容易加载类。
添加Forecast->toArray()
添加Location->toArray()
添加WeatherStations（观测站）
添加TextualForecasts
添加Location->getForecastAt($time)，获取特定unixtime的预报
添加测试。98.15%代码覆盖率（当yr返回HTTP 500时无法达到覆盖率）
在所有类中添加更多异常和错误检查
phpdoc清理

示例

这些示例需要您已经包含autoload.php（或使用自动加载器）

当前预报

$yr = Yr\Yr::create("Norway/Vestfold/Sandefjord/Sandefjord", "/tmp");

$forecast = $yr->getCurrentForecast();
printf("Time: %s to %s\n", $forecast->getFrom()->format("H:i"), $forecast->getTo()->format("H:i"));
printf("Temp: %s %s\n", $forecast->getTemperature(), $forecast->getTemperature('unit'));
printf("Wind: %smps %s\n", $forecast->getWindSpeed(), $forecast->getWindDirection('name'));

Time: 16:00 to 17:00
Temp: 8 celsius 
Wind: 5.7mps South-southwest

明天的预报

$yr = Yr\Yr::create("Norway/Vestfold/Sandefjord/Sandefjord", "/tmp");

foreach($yr->getPeriodicForecasts(strtotime("tomorrow"), strtotime("midnight second day") - 1/*sec*/) as $forecast) {
    printf("Time: %s, %s degrees\n", $forecast->getFrom()->format("H:i"), $forecast->getTemperature());
}

Time: 00:00, 5 degrees
Time: 06:00, 2 degrees
Time: 12:00, 8 degrees
Time: 18:00, 7 degrees

今天剩余时间的每小时预报

$yr = Yr\Yr::create("Norway/Vestfold/Sandefjord/Sandefjord", "/tmp");

foreach($yr->getHourlyForecasts(strtotime("now"), strtotime("tomorrow") - 1/*sec*/) as $forecast) {
    printf("Time: %s, %s degrees\n", $forecast->getFrom()->format("H:i"), $forecast->getTemperature());
}

Time: 20:00: 5 degrees
Time: 21:00: 4 degrees
Time: 22:00: 3 degrees
Time: 23:00: 3 degrees
