Working with IAM policies with AWS SDK for PHP Version 3

You grant permissions to a user by creating a policy. A policy is a document that lists the actions that a user can perform and the resources those actions can affect. By default, any actions or resources that are not explicitly allowed are denied. Policies can be created and attached to users, groups of users, roles assumed by users, and resources.

The following examples show how to:

Create a managed policy using CreatePolicy.
Attach a policy to a role using AttachRolePolicy.
Attach a policy to a user using AttachUserPolicy.
Attach a policy to a group using AttachGroupPolicy.
Remove a role policy using DetachRolePolicy.
Remove a user policy using DetachUserPolicy.
Remove a group policy using DetachGroupPolicy.
Delete a managed policy using DeletePolicy.
Delete a role policy using DeleteRolePolicy.
Delete a user policy using DeleteUserPolicy.
Delete a group policy using DeleteGroupPolicy.

All the example code for the AWS SDK for PHP is available here on GitHub.

Credentials

Before running the example code, configure your AWS credentials, as described in Credentials. Then import the AWS SDK for PHP, as described in Basic usage.

Create a policy

Imports


require 'vendor/autoload.php';

use Aws\Exception\AwsException;
use Aws\Iam\IamClient;

Sample Code


$client = new IamClient([
    'profile' => 'default',
    'region' => 'us-west-2',
    'version' => '2010-05-08'
]);

$policyArn = 'arn:aws:iam::aws:policy/AmazonDynamoDBFullAccess';

try {
    $attachedRolePolicies = $client->getIterator('ListAttachedRolePolicies', ([
        'RoleName' => $roleName,
    ]));
    if (count($attachedRolePolicies) > 0) {
        foreach ($attachedRolePolicies as $attachedRolePolicy) {
