geoPHP就绪属性/元数据

Question

这个想法是在循环geoJson文件中的所有exisint特征时检索properties。我有一个像这样的geoJson文件：

{
    "type": "FeatureCollection",
    "features": [{
        "type": "Feature",
        "properties": {
            "region_name": "my_region",
            "province_name": "my_province",
            ...
        },
        "geometry": {
            "type": "Polygon",
            "coordinates": [
                [
                    [
                        16.45477294921875,
                        43.51619059561274
                    ],
                    [
                        16.450481414794922,
                        43.50772499687011
                    ],
                    [
                        16.470909118652344,
                        43.5019975949657
                    ],
                    [
                        16.481552124023438,
                        43.51021500212034
                    ],
                    [
                        16.475543975830078,
                        43.518306809754804
                    ],
                    [
                        16.45477294921875,
                        43.51619059561274
                    ]
                ]
            ]
        }
    }]
}

尝试使用geoPHP读取它，我使用：

$geoData = geoPHP::load(file_get_contents("path/to/myGeoJson-File.json"),'json');

当转储结果变量时，它没有任何属性字段/数据

                )

        )

    [geos:Geometry:private] => 
    [srid:protected] => 
)

有人解决我如何准备好properties吗？

请注意：geoPHP已成功安装geos extension
