This code may not work yet, but it should soon!
// First we load the geometry object and use the SQL back-end for processing
$geometry1 = new Geometry(array(
'handler_type' => 'sql'
));
// Next we feed it the geometry we want to work with
$geometry1 -> setText("POLYGON((1 1,5 1,5 5,1 5,1 1),(2 2,2 3,3 3,3 2,2 2))");
// Let's load another geometry, and load it with X and Y data.
$geometry2 = new Geometry(
'handler_type' => 'sql'
'lat' => 23,
'lon' => 76,
));
// Test whether they intersect
if ($geometry1 -> intersect($geometry2)) {
drupal_set_message("those geometries intersect!");
// Tell the user about the center of geomtry1
$lon = $geomtry1->centroid()->getY();
$lat = $geomtry1->centroid()->getX();
drupal_set_message("The center of this polygon is at: Lat: " . $lat . ", Lon: " . $lon);
}Some Common Methods
setText - set the data using WKT
getText - get the data in WKT format
setBinary - get the data using WKB
getBinary - set the data using WKB
getX - get the X value (only works for points)
getY - get the Y value (only works for points)
