How to use contains method ?

nakasix commented 5 years ago

Hello,

I have this code in PHP :

# Load my point
$obj_geophp_point = geoPHP::load("POINT($flt_latitude $flt_longitude)");

#Load my KML map
$str_kml = file_get_contents(FCPATH . 'misc/pacwan/map.kml');
$obj_geophp_kml = geoPHP::load($str_kml,'kml');

# Get all Polygon
$ary_components = $obj_geophp_kml->getComponents();

# Foreach Polygon, test the point.
foreach ($ary_components as $value) {
    var_dump($value->contains($obj_geophp_point));
}

My point is in Polygon, but the "contains" function always return "false". Is this an error of use? Could you help me?

Thanx,

Do you have GEOS installed? Contains is an advanced method requires GEOS. See here: https://geophp.net/api.html#user-content-methods-1

In my fork, I have a basic native implementation for Polygons: https://github.com/funiq/geoPHP/blob/master/src/Geometry/Polygon.php#L301
