# Introducere

This extension provides access to the functionality of messaging and queueing systems, such as the IBM WebSphere MQSeries family of products, from PHP scripts. The interface is designed to make it extremely simple to do the more commonly required tasks such as deliver simple text messages to queues while still allowing skilled users to do more complex messaging operations. For many users the complexities of setting up numerous options can be simply ignored.

The SAM extension is a framework that provides a very simple API that can be used to access a number of messaging middleware systems. Currently the package includes built-in support for the MQTT (MQ Telemetry Transport) messaging protocol and support for the IBM Messaging and Queuing middleware products. SAM is designed to be readily extended to support other messaging systems and extension modules may be written in C or PHP.
