Hello to everyone,

use PHPCoord\CoordinateReferenceSystem\Geographic2D;
use PHPCoord\CoordinateReferenceSystem\Projected;
use PHPCoord\Point\ProjectedPoint;

// Centre of Colosseum
$from = ProjectedPoint::createFromEastingNorthing(Projected::fromSRID(Projected::EPSG_MONTE_MARIO_ITALY_ZONE_2), new Metre(2311958), new Metre(4640635));
$toCRS = Geographic2D::fromSRID(Geographic2D::EPSG_WGS_84);
$to = $from->convert($toCRS);

$latitude = $to->getLatitude()->asDegrees()->getValue(); // 41.890190969258
$longitude = $to->getLongitude()->asDegrees()->getValue(); // 12.492307541037
