Geospatial Queries
You can execute some special queries when using geospatial indexes like checking for documents within a rectangle or circle.
Mapping
First, setup some documents like the following:
<?php/** * @Document * @Index(keys={"coordinates"="2d"}) */class City{ /** @Id */ public $id; /** @Field(type="string") */ public $name; /** @EmbedOne(targetDocument=Coordinates::class) */ public $coordinates;}/** @EmbeddedDocument */class Coordinates{ /** @Field(type="float") */ public $x; /** @Field(type="float") */ public $y;}Near Query
Now you can execute queries against these documents like the
following. Check for the 10 nearest cities to a given longitude
and latitude with the near($longitude, $latitude) method:
<?php$cities = $this->dm->createQuery(City::class) ->field('coordinates')->near(-120, 40) ->execute();
