phpgeo is a PHP library providing abstractions for geographical coordinates, polylines, polygons, and bounds with support for different ellipsoids. It enables high-precision calculations such as distances between points, track lengths, and geofence checks.

Use cases

• calculate the distance between two GPS coordinates in PHP
• compute the length of a GPS track or polyline
• check whether a point is inside a polygon geofence
• simplify a GPS track with the Douglas-Peucker algorithm
• convert coordinates between formats and ellipsoids
• calculate the area of a polygon from coordinates

When to choose

• you need precise geodesic distance calculations (Haversine/Vincenty) in a PHP project
• you work with GPS tracks, polylines, or polygons and need geometry helpers
• you want a lightweight, well-documented pure-PHP geo library with no heavy dependencies

When to avoid

• you need a full geospatial database or spatial SQL features (use PostGIS instead)
• you need map rendering, tile servers, or routing engines
• your project runs on PHP below 8.2 without using an older library version
