README 文档

README

A simple (Laravel compatible) library for fetching and decoding METARs. (Soon to be more than this, however)

Prerequisites

Laravel is now required for this library to work properly (due to use of Laravel's Cache and Log system)

Installation

Using Composer:

$ composer require cobaltgrid/aviation-weather

This will ensure that all required dependencies will be installed automatically.

Usage

At the moment, Aviation Weather only support ICAO codes. You can load a METAR by passing the ICAO code when you construct the class.

use Cobaltgrid\Aviation\Weather;
...
$weather = new Weather("EGKK");
$metar = $weather->latest_metar(); // Returns a Cobaltgrid\Aviation\Weather\Metar object

Metar Object Methods

Method	Description
raw_response()	This gets you the raw JSON from the data source (SimpleXMLElement)
raw()	This gets you the raw JSON METAR data from the data source (SimpleXMLElement)
raw_string()	The raw METAR string (String)
icao()	The ICAO code of the station (String)
time()	A carbon object for the METAR's observation time (Carbon)
latitude()	A float of the latitude of the observation (Float)
longitude()	A float of the longitude of the observation (Float)
temperature()	The temperature, in degrees celsius (Float)
dewpoint()	The dew point, in degrees celsius (Float)
wind_direction()	The wind direction, in whole degrees. If 0, this indicates a variable wind. (Int)
wind_speed()	The wind speed, in knots. If both speed and direction are 0, wind is 'calm' (Int)
wind_gust()	The wind gust, in knots (Int)
visibility($unit="m")	Options: "km", "m", "nm", "mi". Gives the visibility in the chosen units. (Float/Int)
qnh($unit="hpa")	Options: "hpa", "hg". Gives the QNH pressure setting in the chosen units. (Float/Int)
weather_array()	An array of raw weather codes (i.e "-HZ +SH" etc) (Array)
weather()	An array of decoded weather codes of the format: `['code' => '-RA', 'human' => 'Light Rain']` (Array)
sky_cover()	An array of decoded cloud cover. Each array item is an array with the following format: `['type' => 'SCT', 'type_human' => 'Scattered', 'height' => 2000]` . Height is in feet.
flight_cat()	An indication of the type of flying permitted by the weather. Example values: MVFR, IFR, LVFR, etc.
toArray()	Converts the above into an array format

cobaltgrid/aviation-weather 适用场景与选型建议

cobaltgrid/aviation-weather 是一款基于 PHP 开发的 Composer 扩展包，目前已累计 48 次下载、GitHub Stars 达 4，最近一次更新时间为 2017 年 05 月 30 日，在 PHP 生态内属于活跃度较高的组件。

它主要适用于以下技术方向：「weather」「METAR」「aviation」等业务场景。在实际项目中，围绕这些方向常见需要落地的问题包括：接口对接、性能调优、并发安全、与既有框架（Laravel / ThinkPHP / Yii / Webman 等）的兼容适配，以及生产环境的日志埋点与稳定性保障。

我们在过去多个企业项目中使用过 cobaltgrid/aviation-weather 或与其功能相近的方案，如果你在选型或落地过程中遇到问题，例如 版本兼容、二次改造、私有化封装、与内部系统对接、生产 BUG 排查，欢迎联系我们协助评估。
