Imports

require "vendor/autoload.php";

use Aws\Exception\AwsException;
use Aws\S3\S3Client;

Sample Code

$s3Client = new S3Client([
    'profile' => 'default',
    'region' => 'us-west-2',
    'version' => '2006-03-01'
]);

$bucket = 'my-s3-bucket';

// Get the policy of a specific bucket
try {
    $resp = $s3Client->getBucketPolicy([
        'Bucket' => $bucket
    ]);
    echo "Succeed in receiving bucket policy:\n";
    echo $resp->get('Policy');
    echo "\n";
} catch (AwsException $e) {
    // Display error message
    echo $e->getMessage();
    echo "\n";
}

// Deletes the policy from the bucket
try {
    $resp = $s3Client->deleteBucketPolicy([
        'Bucket' => $bucket
    ]);
    echo "Succeed in deleting policy of bucket: " . $bucket . "\n";
} catch (AwsException $e) {
    // Display error message
    echo $e->getMessage();
    echo "\n";
}

// Replaces a policy on the bucket
try {
    $resp = $s3Client->putBucketPolicy([
