# AWS PHP SDK

This guide assumes that you have followed the steps in the [Getting Started](/docs/get-started/.md) guide, and have the access keys available.

You may continue to use the AWS PHP SDK as you normally would, but with the endpoint set to Tigris at <https://t3.storage.dev>.

## Getting started[​](#getting-started "Direct link to Getting started")

This example uses the [AWS PHP SDK v3](https://packagist.org/packages/aws/aws-sdk-php) and reads the default credentials file or the environment variables `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY`.

```
<?php

    require 'vendor/autoload.php';



    $bucket_name = 'foo-bucket';



    $s3 = new Aws\S3\S3Client([

        'region' => 'auto',

        'endpoint' => 'https://t3.storage.dev',

        'version' => 'latest',

    ]);



    # Lists all of your buckets

    print("\nMy buckets now are:\n");



    $promise = $s3->listBucketsAsync();

    $result = $promise->wait();



    foreach ($result['Buckets'] as $bucket) {

        print("\n");

        print($bucket['Name']);

    }



    # Put an object into the bucket

    $file_name = "bar-file-" . uniqid();

    try {

        $s3->putObject([

            'Bucket' => $bucket_name,

            'Key' => $file_name,

            'SourceFile' => 'bar.txt'

        ]);

        echo "Uploaded $file_name to $bucket_name.\n";

    } catch (Exception $exception) {

        echo "Failed to upload $file_name with error: " . $exception->getMessage();

        exit("Please fix error with file upload before continuing.");

    }



    try {

        $file = $s3->getObject([

            'Bucket' => $bucket_name,

            'Key' => $file_name,

        ]);

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

        $body->rewind();

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

    } catch (Exception $exception) {

        echo "Failed to download $file_name from $bucket_name with error: " . $exception->getMessage();

        exit("Please fix error with file downloading before continuing.");

    }



    try {

        $contents = $s3->listObjects([

            'Bucket' => $bucket_name,

        ]);

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

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

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

        }

    } catch (Exception $exception) {

        echo "Failed to list objects in $bucket_name with error: " . $exception->getMessage();

        exit("Please fix error with listing objects before continuing.");

    }

?>
```

## Using presigned URLs[​](#using-presigned-urls "Direct link to Using presigned URLs")

Presigned URLs can be used with the AWS PHP SDK as follows:

```
<?php

    require 'vendor/autoload.php';



    $bucket_name = 'foo-bucket';



    $s3 = new Aws\S3\S3Client([

        'region' => 'auto',

        'endpoint' => 'https://t3.storage.dev',

        'version' => 'latest',

    ]);



    # Generate a presigned URL to download an object

    $command = $s3->getCommand('GetObject', [

        'Bucket' => $bucket_name,

        'Key' => 'bar.txt',

    ]);



    $request = $s3->createPresignedRequest($command, '+20 minutes');



    echo "Presigned URL to download an object: " . (string) $request->getUri() . "\n";



    # Generate a presigned URL to upload an object

    $command = $s3->getCommand('PutObject', [

        'Bucket' => $bucket_name,

        'Key' => 'bar.txt',

    ]);



    $request = $s3->createPresignedRequest($command, '+20 minutes');



    echo "Presigned URL to upload an object: " . (string) $request->getUri() . "\n";

?>
```

You can now use the URL returned by the `$request->getUri()` to upload or download objects.

### Presigned URLs with custom domains[​](#presigned-urls-with-custom-domains "Direct link to Presigned URLs with custom domains")

You can also use a [presigned URL with a custom domain](/docs/objects/presigned/.md#presigned-url-with-custom-domain) by replacing the bucket host with your custom domain:

```
$brandedURL = str_replace(

    "foo-bucket.t3.storage.dev", "your-domain.example.com", $presignedUrl);

echo "Presigned URL for GET (custom domain): " . $brandedURL . "\n";
```
