Stored coordinates, distances in Twig, configured geocoders and nearest-first lists for Symfony applications.

phil/geo-bundle brings phil/geo into a Symfony application. It maps Coordinates as a Doctrine embeddable of two float columns, adds CoordinatesType to enter a position as two fields, and gives Twig geo_distance(), format_distance, geo_attributes() and geo_schema(). It registers the geocoders the configuration lists, asked in that order and optionally cached, and an IP locator on MaxMind or ipstack. The command phil:geo:maxmind:update downloads the latest MaxMind database, checks it and puts it in place.

It is for Symfony applications where editors enter positions and visitors look for the nearest place. The Stimulus controller distance-sort sorts places by their distance to the visitor in the browser. The browser asks the visitor for the position, and that position never reaches the server. The server publishes the places, blurred when their exact position is private, and knows nothing of who is near which.

Use the bundle when the application runs on Symfony; in other PHP code, or inside a domain model, use phil/geo directly. The Doctrine mapping needs the ORM and can be turned off with doctrine_mapping. The bundle adds no geography of its own: each piece wraps a library type, and the browser computes the same great-circle distance as Coordinates::distanceTo().

Quick start

composer require phil/geo-bundle

// config/bundles.php
return [
    // ...
    Phil\GeoBundle\PhilGeoBundle::class => ['all' => true],
];

<div data-controller="phil--geo-bundle--distance-sort" data-phil--geo-bundle--distance-sort-locate-value="true">
    {% for store in stores %}
        <article {{ geo_attributes(store.position, 3) }}>{{ store.name }} <span data-distance></span></article>
    {% endfor %}
</div>

Requirements

PHP 8.5 or later with ext-intl, and ext-zlib for phil:geo:maxmind:update; phil/geo 0.1; symfony/config, symfony/dependency-injection, symfony/form and symfony/options-resolver 8.2 or later. Doctrine ORM and Twig are optional; the controller needs @hotwired/stimulus 3, which the application provides.
