php-awsHow can I use PHP to list objects stored in AWS S3?

Using PHP, you can list objects stored in AWS S3 by using the listObjectsV2 method from the AWS SDK for PHP.

The following example code will list all objects stored in an S3 bucket:

<?php

require 'vendor/autoload.php';

use Aws\S3\S3Client;

$s3 = new S3Client([
    'region'  => 'us-west-2',
    'version' => 'latest',
    'credentials' => [
        'key'    => 'YOUR_AWS_ACCESS_KEY_ID',
        'secret' => 'YOUR_AWS_SECRET_ACCESS_KEY',
    ]
]);

$objects = $s3->listObjectsV2([
    'Bucket' => 'YOUR_S3_BUCKET_NAME'
]);

foreach ($objects['Contents'] as $object) {
    echo $object['Key'] . PHP_EOL;
}

This example code will output the name of each object stored in the S3 bucket:

object1.txt
object2.txt
object3.txt

The code is broken down into the following parts:

1. Require the autoloader from the AWS SDK for PHP: require 'vendor/autoload.php';
2. Use the S3Client class from the AWS SDK for PHP: use Aws\S3\S3Client;
3. Create a new S3Client instance with your AWS credentials:

$s3 = new S3Client([
    'region'  => 'us-west-2',
    'version' => 'latest',
    'credentials' => [
        'key'    => 'YOUR_AWS_ACCESS_KEY_ID',
        'secret' => 'YOUR_AWS_SECRET_ACCESS_KEY',
    ]
]);

4. List the objects in the S3 bucket using the listObjectsV2 method:

$objects = $s3->listObjectsV2([
    'Bucket' => 'YOUR_S3_BUCKET_NAME'
]);

5. Iterate over the list of objects and output the name of each object:

foreach ($objects['Contents'] as $object) {
    echo $object['Key'] . PHP_EOL;
}
