PHP GeoJSON implementation library

GeoJSON is a format for encoding various geographical data structures, a geospatial information data exchange format based on Javascript object representation. GeoJSON objects can represent geometries, features, or feature collections. GeoJSON supports the following geometry types: point, line, polygon, multipoint, multiline, polygon, and geometry collection. Features in GeoJSON include a geometric object and other attributes, and feature collections represent a series of features.

A complete GeoJSON data structure is always an object (in JSON terms). In GeoJSON, objects are composed of name/value pairs - also called collections of members. For each member, the name is always a string. The value of a member is either a string, a number, an object, an array, or one of the following text constants: "true", "false", and "null". Arrays are composed of elements whose values are as mentioned above.

GeoJSON always consists of a single object. This object (referring to the GeoJSON object below) represents a geometry, feature, or collection of features.
