Implement spatial PHP types and their geometric and geographic classes.
If you want to persist spatial data in a database, you should use the longitude-one/doctrine2-spatial package.
composer require longitude-one/spatial-types
use LongitudeOne\Spatial\Types\Geometry\Point;
$point = new Point(1, 2);
echo $point->getX(); // 1
echo $point->getY(); // 2
$lineString = new LineString([
new Point(1, 2),
new Point(3, 4),
new Point(5, 6),
], 4326);
$lineString->getSrid(); // 4326
