You need these while working with AWS S3 bucket to upload any files or folders.

• AWS Access Key
• AWS Secret Key
• Bucket Name

Step #1 – AWS S3 Connection

// Instantiate an Amazon S3 client.
$s3Client = new S3Client([
    'version' => 'latest',
    'region'  => 'us-east-1', // Your AWS region
    'credentials' => [
        'key'    => $awsAccessKey,
        'secret' => $awsSecretKey
    ]
]);

Step #2 – Upload File To Bucket

$result = $s3Client->putObject([
    'Bucket' => $bucket,
    'Key'    => $file_Path,
    'Body'   => fopen($file_Path, 'r'),
    'ACL'    => 'public-read',
]);

Open upload-project.php file and write this complete code into it.

<?php

require 'vendor/autoload.php';

use Aws\S3\S3Client;

// List all files and folders in a main folder
function listFolderFiles($dir)
{
    $fileInfo     = scandir($dir);
    $allFileLists = [];

    foreach ($fileInfo as $folder) {
        if ($folder !== '.' && $folder !== '..') {
            if (is_dir($dir . DIRECTORY_SEPARATOR . $folder) === true) {
                $allFileLists[] = listFolderFiles($dir . DIRECTORY_SEPARATOR . $folder);
            } else {
                $allFileLists[] = $dir . "/" . $folder;
            }
        }
    }

    return $allFileLists;
}

// Upload a complete folder to AWS
function uploadFolderToAWS($dirLists)
{
    foreach ($dirLists as $dir) {

        if ($dir !== '.' && $dir !== '..') {
            if (is_array($dir) === true) {
                // Array
                uploadFolderToAWS($dir);
            } else {
                // file
                uploadFileToS3Bucket($dir);
            }
        }
    }
}

// Upload file to AWS S3
function uploadFileToS3Bucket($file_Path)
{
    $awsAccessKey = 'XXXX';
    $awsSecretKey = 'YYYYYYYYYY';
    $bucket = 'your-bucket-name';

    try {
        // Instantiate an Amazon S3 client.
        $s3Client = new S3Client([
            'version' => 'latest',
            'region'  => 'us-east-1', // Your AWS region
            'credentials' => [
                'key'    => $awsAccessKey,
                'secret' => $awsSecretKey
            ]
        ]);

        $result = $s3Client->putObject([
            'Bucket' => $bucket,
            'Key'    => $file_Path,
            'Body'   => fopen($file_Path, 'r'),
            'ACL'    => 'public-read',
        ]);
        echo "<pre>";
        print_r($result);
    } catch (Aws\S3\Exception\S3Exception $e) {
        echo "There was an error uploading the file.\n";
        echo $e->getMessage();
    }
}


$folderToMove = "your-project-folder";

$dirLists = listFolderFiles($folderToMove);

// Upload a complete site
uploadFolderToAWS($dirLists);

Inside above code, you can see it contains 3 functions.

• listFolderFiles() – This function will list all files and folders from given directory
• uploadFolderToAWS() – This function will send a single file to upload to AWS and also if the given directory contains subfolders then it will scan that also.
• uploadFileToS3Bucket() – This function will upload file to AWS S3 bucket.

For this example, suppose $folderToMove = “your-project-folder”; contains subfolders and files.

$dirLists = listFolderFiles($folderToMove); This will list all files and folders inside it.

We are uploading each folder and files from above code to this uploadFolderToAWS($dirLists);

Then step by step above function will scan in two cases – First if it is a folder then same process will execute and again it scans the subfolder. In the second case if it is a file then directly it will upload file to AWS S3 bucket.
