# Amazon SQS examples using the Amazon SDK for PHP Version 3
<a name="sqs-examples"></a>

Amazon Simple Queue Service (SQS) is a fast, reliable, scalable, fully managed message queuing service. Amazon SQS lets you decouple the components of a cloud application. Amazon SQS includes standard queues with high throughput and at-least-once processing, and FIFO queues that provide FIFO (first>-in, first>-out) delivery and exactly-once processing.

All the example code for the Amazon SDK for PHP Version 3 is available [here on GitHub](https://github.com/awsdocs/aws-doc-sdk-examples/tree/main/php/example_code).
