IP Location

A simple set of third-party service implementations for determining a geographical location using an IP address.

This library is based on the screencasts of the knowledge base Deworker.pro

Installation

The preferred way to install this extension is through composer

composer require nuthouse-cis/ip-location

Or add to your composer.json file

{
  "require": {
    "nuthouse-cis/ip-location": "*"
  }
}

Examples

Basic usage

require 'vendor/autoload.php';
/** @var $locator \NuthouseCIS\IPLocation\Locator */
$ip = new \NuthouseCIS\IPLocation\Ip('8.8.8.8');
$location = $locator->locate($ip);

if ($location
    && ($location->getCountry()->getIsoAlpha2() === 'US'
        || $location->getCountry()->getIsoAlpha3() === 'USA'
        || $location->getCountry()->getName() === 'United States')
) {
    // Do some stuff
}

Also placed JSON decorator:

/** @var $location \NuthouseCIS\IPLocation\Location\Location */
$decorator = new \NuthouseCIS\IPLocation\Decorators\LocationJsonDecorator($location);
print json_encode($decorator);

Cache Locator

This locator using PSR-16 Simple Cache interface for caching result of another implementation of \NuthouseCIS\IPLocation\Locator

/**
 * @var $simpleCacheIterface \Psr\SimpleCache\CacheInterface
 * @var $adapter \NuthouseCIS\IPLocation\Locator
 */
$locator = new \NuthouseCIS\IPLocation\Locators\CacheLocator(
    $adapter,
    $simpleCacheIterface,
    10 * 60,
    'adapter1-'
);

Mute Locator

Mute locator catch all Exceptions and use implementation of \NuthouseCIS\IPLocation\Handlers\ErrorHandler to handle they

$errorHandler = new class implements \NuthouseCIS\IPLocation\Handlers\ErrorHandler {
    public function handle(Exception $exception): void
    {
        // Do some stuff with exception
    }
};
/**
 * @var $adapter \NuthouseCIS\IPLocation\Locator
 */
$locator = new \NuthouseCIS\IPLocation\Locators\MuteLocator(
    $adapter,
    $errorHandler
);

Also, you can use \NuthouseCIS\IPLocation\Handlers\PsrLogErrorHandler

/**
 * @var $logger \Psr\Log\LoggerInterface
 */
$errorHandler = new \NuthouseCIS\IPLocation\Handlers\PsrLogErrorHandler(
    $logger,
    \Psr\Log\LogLevel::ERROR
);

Chain Locator

Chain locator returns the most complete result from all passed implementations of \NuthouseCIS\IPLocation\Locator

/**
 * @var $adapters \NuthouseCIS\IPLocation\Locator[]
 */
$locator = new \NuthouseCIS\IPLocation\Locators\ChainLocator(
    ...$adapters
);
