# PHP client libraries

> Our PHP SDK gives you access to the Contentful APIs and their features | Access to the Content Delivery and Management APIs for PHP

Our PHP SDK client libraries give you access to our [APIs](/developers/docs/references/api-basics) and their features.

### Content Delivery API client library

This PHP SDK client library interacts with the Content Delivery API, a read-only API for retrieving content from Contentful. All content, both JSON and binary, is fetched from the server closest to a user's location using our global CDN.
