About this fork

The primary objective of this fork is to modernize the source code by transitioning to a contemporary version of PHP, incorporating namespaces and introducing new features.

GeoPHP README

GeoPHP is a open-source native PHP library for doing geometry operations. It is written entirely in PHP and can therefore run on shared hosts. It can read and write a wide variety of formats: WKT (including EWKT), WKB (including EWKB), GeoJSON, KML, GPX, and GeoRSS. It works with all Simple-Feature geometries (Point, LineString, Polygon, GeometryCollection etc.) and can be used to get centroids, bounding-boxes, area, and a wide variety of other useful information.

geoPHP also helpfully wraps the GEOS php extension so that applications can get a transparent performance increase when GEOS is installed on the server. When GEOS is installed, geoPHP also becomes fully compliant with the OpenGIS® Implementation Standard for Geographic information. With GEOS you get the full-set of openGIS functions in PHP like Union, IsWithin, Touches etc. This means that applications get a useful "core-set" of geometry operations that work in all environments, and an "extended-set"of operations for environments that have GEOS installed.

See the 'getting started' section below for references and examples of everything that geoPHP can do.

This project is currently looking for co-maintainers. If you think you can help out, please send me a message. Forks are also welcome, please issue pull requests and I will merge them into the main branch.
