IAM examples using SDK for PHP - AWS SDK for PHP

IAM examples using SDK for PHP

The following code examples show you how to perform actions and implement common scenarios by using the AWS SDK for PHP with IAM.

Actions are code excerpts from larger programs and must be run in context. While actions show you how to call individual service functions, you can see actions in context in their related scenarios and cross-service examples.

Scenarios are code examples that show you how to accomplish a specific task by calling multiple functions within the same service.

Each example includes a link to GitHub, where you can find instructions on how to set up and run the code in context.

Actions

Scenarios

The following code example shows how to create a user and assume a role.

Warning

To avoid security risks, don't use IAM users for authentication when developing purpose-built software or working with real data. Instead, use federation with an identity provider such as AWS IAM Identity Center.

  • Create a user with no permissions.

  • Create a role that grants permission to list Amazon S3 buckets for the account.

  • Add a policy to let the user assume the role.

  • Assume the role and list S3 buckets using temporary credentials, then clean up resources.
