I experience a memory leak

[kasperkamperman]

I experiment some kind of memory leak when converting coordinates for multiple times.

Do you see any issues with this code?

PHP 8.0.6
PHPCoord 4.3
Datapack Europe 1.0

require_once __DIR__ . '/vendor/autoload.php';

use PHPCoord\CoordinateReferenceSystem\Projected;
use PHPCoord\CoordinateReferenceSystem\Geographic2D;
use PHPCoord\ProjectedPoint;
use PHPCoord\UnitOfMeasure\Length\Metre;

function convertCoord($easting, $northing)
{
    $crs = Projected::fromSRID(Projected::EPSG_AMERSFOORT_RD_NEW);
    $from = ProjectedPoint::createFromEastingNorthing(
        new Metre($easting),
        new Metre($northing),
        $crs
    );

    $coords = (string) $from->convert(Geographic2D::fromSRID(Geographic2D::EPSG_WGS_84));
    $coords = explode(",", trim($coords, '()'));

    $lonlat[] = floatval($coords[1]);
    $lonlat[] = floatval($coords[0]);

    return $lonlat;
}

function getPointLonLat()
{
    // of course below will be variables, but I experience the issue even calling this function multiple times.
    $x = 94904.701655864;
    $y = 467709.4147013;

    $lonlat = convertCoord($x, $y);

    return $lonlat;
}

Hello @kasperkamperman

How are you detecting the leak? Running the below shows an unchanging number for me (PHP 8.0.5)

for ($i = 0; $i < 1000; $i++) {
   getPointLonLat();
   echo memory_get_usage() . "\n";
}

Thanks. I couldn't reproduce the error standalone.

Probably a combination with loading a large file and getting the UnknownConversionException error. Which I could solve by passing the true, to the convert method:
$from->convert(Geographic2D::fromSRID(Geographic2D::EPSG_WGS_84), true)
