Question 1

How do I parse GeoJSON from a string in PHP using this library?

Accepted Answer

Use the library's deserialization methods to convert JSON strings into PHP objects; invalid data will throw exceptions, ensuring spec compliance. Check USAGE.md for code examples.

Question 2

Is jmikola/geojson better than just using json_decode for GeoJSON?

Accepted Answer

Yes, for strict validation and object-oriented access. While json_decode parses JSON, this library enforces GeoJSON standards and provides structured classes, reducing manual checks.

Question 3

Can I use it with Laravel for building geospatial APIs?

Accepted Answer

Yes, install via Composer and integrate the classes into Laravel controllers or services, but no Laravel-specific bindings or Eloquent support are included out of the box.

Question 4

How to validate GeoJSON data before saving to a database?

Accepted Answer

Deserialize the data using the library; if it doesn't throw an error, it's valid. You can then store the serialized JSON or map it to your database schema.

Question 5

Does it support 3D coordinates or custom properties in GeoJSON?

Accepted Answer

Yes, it supports 3D coordinates as per the spec, and custom properties can be added to feature objects, though validation focuses on the core format structure.

Question 6

What PHP versions are compatible?

Accepted Answer

The library requires PHP 7.2 or higher, as noted in the Composer package details; ensure your environment meets this for installation and usage.

Question 7

How to convert WKT to GeoJSON with this library?

Accepted Answer

It doesn't handle WKT conversion directly; you'll need an additional library for WKT parsing and then use this library to create GeoJSON objects from the parsed data.
