OpenCage Geocoding API Library for PHP
A PHP library to use the OpenCage geocoding API.
Build Status / Code Quality
Overview
This library attempts to use the CURL extension to access the OpenCage Geocoding API. If CURL support is not available, the library falls back to using fopen wrappers.
To use the library you must either have the CURL extension compiled into your version
of PHP. Alternatively configure the use of fopen wrappers via the allow_url_fopen
directive in your php.ini.
Authentication
You need an API key, which you can sign up for here.
Tutorial
You can find a comprehensive tutorial for using this module on the OpenCage site.
Installation
With Composer
The recommended - and easiest way - to install is via Composer.
Require the library in your project's composer.json file.
$ composer require opencage/geocodeImport the Geocoder class.
require "vendor/autoload.php";The old fashioned way
See the file demo/geocode.php
Geocoding
$geocoder = new \OpenCage\Geocoder\Geocoder('YOUR-API-KEY');
$result = $geocoder->geocode('82 Clerkenwell Road, London');
print_r($result);Reverse geocoding
$geocoder = new \OpenCage\Geocoder\Geocoder('YOUR-API-KEY');
$result = $geocoder->geocode('43.831,4.360'); # latitude,longitude (y,x)
print $result['results'][0]['formatted'];
// 3 Rue de Rivarol, 30020 Nîmes, FranceSet optional parameters
See the full list at: https://opencagedata.com/api#optional-params
$result = $geocoder->geocode('6 Rue Massillon, 30020 Nîmes, France', [
'language' => 'fr',
'countrycode' => 'fr'
]);
if ($result && $result['total_results'] > 0) {
$first = $result['results'][0];
print $first['geometry']['lng'] . ';' . $first['geometry']['lat'] . ';' . $first['formatted'] . "\n";
// 4.360081;43.8316276;6 Rue Massillon, 30020 Nîmes, Frankreich
}Set a proxy URL
$geocoder->setProxy('http://proxy.example.com:1234');
$result = $geocoder->geocode("Brandenburger Tor, Berlin");
print_r($result['results'][0]['formatted']);
// Brandenburger Tor, Unter den Linden, 10117 Berlin, Germany
print_r($result['results'][0]['geometry']);
