1. 8 geoPHP/lib/adapters/GoogleGeocode.class.php \GoogleGeocode::read()

Read an address string or array geometry objects

Parameters

string - Address to geocode:

string - Type of Geometry to return. Can either be 'points' or 'bounds' (polygon):

Geometry|bounds-array - Limit the search area to within this region. For example: by default geocoding "Cairo" will return the location of Cairo Egypt. If you pass a polygon of illinois, it will return Cairo IL.

return_multiple - Return all results in a multipoint or multipolygon:

Return value

Geometry|GeometryCollection
