# Managing IAM users with AWS SDK for PHP Version 3
<a name="iam-examples-managing-users"></a>

An IAM user is an entity that you create in AWS to represent the person or service that uses it to interact with AWS. A user in AWS consists of a name and credentials.

The following examples show how to:
+ Create a new IAM user using [CreateUser](https://docs.aws.amazon.com/aws-sdk-php/v3/api/api-iam-2010-05-08.html#createuser).
+ List IAM users using [ListUsers](https://docs.aws.amazon.com/aws-sdk-php/v3/api/api-iam-2010-05-08.html#listusers).
+ Update an IAM user using [UpdateUser](https://docs.aws.amazon.com/aws-sdk-php/v3/api/api-iam-2010-05-08.html#updateuser).
+ Retrieve information about an IAM user using [GetUser](https://docs.aws.amazon.com/aws-sdk-php/v3/api/api-iam-2010-05-08.html#getuser).
+ Delete an IAM user using [DeleteUser](https://docs.aws.amazon.com/aws-sdk-php/v3/api/api-iam-2010-05-08.html#deleteuser).

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

## Credentials

Before running the example code, configure your AWS credentials, as described in [Authenticating with AWS using AWS SDK for PHP Version 3](credentials.md). Then import the AWS SDK for PHP, as described in [Installing the AWS SDK for PHP Version 3](getting-started_installation.md).
