Message:

I'm using the aws sdk to connect to an s3 bucket. I have built an IAM Policy to allow read using "s3:GetObject", "s3:GetObjectAcl" and "s3:ListBucket" and I can use the AWS cli to view objects and list files (including with listobjectsv2). When I use:

    $file = $s3client->getObject([

        'Bucket' => $bucket,

        'Key' => $key,

    ]);

    $body = $file->get('Body');

    $body->rewind();

    echo "Downloaded the file and it begins with: {$body->read(26)}.\n";

I can view file contents but when I try:

 $contents = $s3client->listObjectsV2([

        'Bucket' => $bucket

    ]);

    echo "The contents of your bucket are: \n";

    foreach ($contents['Contents'] as $content) {

        echo $content['Key'] . "\n";

I receive a super helpful error:

Fatal error: Uncaught Error: Class 'SimpleXMLElement' not found in /var/www/html/vendor/aws/aws-sdk-php/src/Api/Parser/PayloadParserTrait.php:39 Stack trace: ....

It goes on but I figure it's all trash so not continuing.
I grabbed the code straight from: https://docs.aws.amazon.com/code-samples/latest/catalog/php-s3-s3_basics-GettingStartedWithS3.php.html
Any suggestions on what is wrong?

My Answer:
the ListObjectsV2 action on the bucket. Here is an example of how you can use the ListObjectsV2 operation in a PHP page:

php

require 'vendor/autoload.php'; // Include the AWS SDK for PHP

use Aws\S3\S3Client;

// Set up the AWS credentials
$credentials = new Aws\Credentials\Credentials('YOUR_ACCESS_KEY', 'YOUR_SECRET_KEY');

// Set up the S3 client
$s3Client = new S3Client([
'version' => 'latest',
'region' => 'us-east-1',
'credentials' => $credentials
]);

// Specify the bucket name
$bucket = 'YOUR_BUCKET_NAME';

// List objects in the bucket
$objects = $s3Client->listObjectsV2([
'Bucket' => $bucket
]);

// Output the object keys
foreach ($objects['Contents'] as $object) {
echo $object['Key'] . "\n";
}

?>


Make sure to replace 'YOUR_ACCESS_KEY', 'YOUR_SECRET_KEY', and 'YOUR_BUCKET_NAME' with your actual AWS credentials and bucket name. This code will list all the object keys in the specified S3 bucket.
