OpenWeatherMap PHP API

A PHP 7.0+ API to retrieve and parse global weather data from OpenWeatherMap.org. This library aims to normalise the provided data and remove some inconsistencies. This library is neither maintained by OpenWeatherMap nor their official PHP API.

Installation

This library can be found on Packagist. The recommended way to install and use it is through Composer.

composer require "cmfcmf/openweathermap-php-api"

You will also need to choose and install two additional dependencies separately:

1. A PSR-17 compatible HTTP factory implementation. A list of HTTP factory implementations is available at Packagist.
2. A PSR-18 compatible HTTP client implementation. A list of HTTP client implementations is available at Packagist.

Example call

<?php
use Cmfcmf\OpenWeatherMap;
use Cmfcmf\OpenWeatherMap\Exception as OWMException;
use Http\Factory\Guzzle\RequestFactory;
use Http\Adapter\Guzzle6\Client as GuzzleAdapter;

// Must point to composer's autoload file.
require 'vendor/autoload.php';

// Language of data (try your own language here!):
$lang = 'de';

// Units (can be 'metric' or 'imperial' [default]):
$units = 'metric';

// You can use every PSR-17 compatible HTTP request factory
// and every PSR-18 compatible HTTP client. This example uses
// `http-interop/http-factory-guzzle` ^1.0 and `php-http/guzzle6-adapter` ^2.0 || ^1.0
// which you need to install separately.
$httpRequestFactory = new RequestFactory();
$httpClient = GuzzleAdapter::createWithConfig([]);

// Create OpenWeatherMap object.
$owm = new OpenWeatherMap('YOUR-API-KEY', $httpClient, $httpRequestFactory);

try {
    $weather = $owm->getWeather('Berlin', $units, $lang);
} catch(OWMException $e) {
    echo 'OpenWeatherMap exception: ' . $e->getMessage() . ' (Code ' . $e->getCode() . ').';
} catch(\Exception $e) {
    echo 'General exception: ' . $e->getMessage() . ' (Code ' . $e->getCode() . ').';
}

echo $weather->temperature;
