 # PHP GBIF client
 
-First attempt of a PHP client for the [GBIF API](https://www.gbif.org/developer/summary). See its sibling projects in [R](https://github.com/ropensci/rgbif), [Python](https://github.com/sckott/pygbif) and [Ruby](https://github.com/sckott/gbifrb). Only occurrences (search and retrieval) are currently supported, but features will be added if this project gets enough funding.

 A [Drupal module](https://www.drupal.org/project/gbif2) uses this client to enable users to list GBIF occurrences with the Views module on their websites.
