OpenCage Geocoding API Library for PHP

A PHP library to use the OpenCage geocoding API.

Build Status / Code Quality

Build Status Kritika Analysis Status PHP version

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.

PHP 5.6, 7 are supported. hhvm 4 is no longer supported.

To use the library you must either have the CURL extension compiled into your version of PHP or 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.

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/geocode

Import the Geocoder class.

require "vendor/autoload.php";

Start geocoding

$geocoder = new \OpenCage\Geocoder\Geocoder('YOUR-API-KEY');
$result = $geocoder->geocode('82 Clerkenwell Road, London');
print_r($result);

The old fashioned way

See the file demo/geocode.php
