==============

Open-source native PHP library for doing geometry operations. Can read and write a wide variety of formats: (E)WKT, (E)WKB, TWKB, GeoJSON, KML, GPX, GeoRSS. Works with all Simple-Feature geometries (Point, LineString, Polygon...) and can be used to get centroids, bounding-boxes, area, etc.

GeoPHP is a open-source native PHP library for doing geometry operations. It is a fork of famous [geoPHP](https://github.com/phayes/geoPHP) library by Patrick Hayes.

Notice about this repo
----------------------

[](#notice-about-this-repo)

*This fork aims to unify the most relevant forks from the original work of phayes/geoPHP*

### Goals

[](#goals)

- Maintain compatibility with current [supported versions of PHP](https://www.php.net/supported-versions.php)
- Keep the unit tests compatible with the latest PHPUnit
- Merge contributions from other [geoPHP forks](https://github.com/phayes/geoPHP/forks), like [funiq](https://github.com/funiq/geoPHP), [swen100](https://github.com/swen100/geoPHP) and others

It is written entirely in PHP and can therefore run on shared hosts. It can read and write a wide variety of formats: WKT (EWKT), WKB (EWKB), TWKB, 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.

Forks and contributions are welcome. Please open [issues](https://github.com/wgirhad/geoPHP/issues), send [pull](https://github.com/wgirhad/geoPHP/pulls) requests and I will merge them into the main branch.
