What does PHP SDK mean?

A PHP SDK is a set of tools, libraries and ready-made functions for developing applications in the PHP programming language. SDK stands for Software Development Kit. It makes it easier for developers to connect with a specific service, platform or API, because they don't have to build all the communication from scratch. An SDK can contain methods for sending requests, working with data, authentication, error handling, documentation or sample code. In e-commerce, a PHP SDK is used, for example, to connect an e-shop to payment gateways, carriers, marketing tools or other external services. Using it can speed up development and reduce the risk of errors during integration.
