# Rest PKI samples - Availability per project

Since we have several samples projects and we are always adding new feature samples, not all feature samples are
available on a given project. The matrix below shows which samples are available on which projects.

We also have some legacy samples projects no longer updated in [PHP 5.3/5.4](https://docs.lacunasoftware.com/en-us/articles/rest-pki/php/legacy), [PHP 5.2](https://docs.lacunasoftware.com/en-us/articles/rest-pki/php/legacy52), and [Node.js SPA](https://docs.lacunasoftware.com/en-us/articles/rest-pki/nodejs/spa).
