How to upload files to S3 using PHP SDK

Alright, uploading files to S3 with PHP? Super simple with the AWS SDK. Let’s break it down.

First, install the AWS SDK for PHP (if you haven’t already):

composer require aws/aws-sdk-php

And then here is an example script

<?php

require 'vendor/autoload.php';

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

// AWS S3 config
$s3 = new S3Client([
    'version' => 'latest',
    'region'  => 'us-east-1', // Change to your region
    'credentials' => [
        'key'    => 'your-access-key',
        'secret' => 'your-secret-key',
    ],
]);

$bucketName = 'your-bucket-name';
$filePath = 'path/to/local/file.txt';
$keyInS3 = 'folder-in-s3/file.txt'; // Where it should be stored in S3

try {
    $s3->putObject([
        'Bucket' => $bucketName,
        'Key'    => $keyInS3,
        'SourceFile' => $filePath,
        'ACL'    => 'public-read', // Or private, depending on your needs
    ]);
    echo "Upload successful!\n";
} catch (AwsException $e) {
    echo "Upload failed: " . $e->getMessage() . "\n";
}

?>
