Storing and Fetching Files with Amazon S3 in PHP
Amazon Web Services (AWS) offers Amazon Simple Storage Service (S3), a cloud storage service that is exceptionally scalable and reliable. It presents developers with a straightforward and cost-effective solution for efficiently storing and retrieving vast quantities of data. This article will delve into the implementation of S3 buckets in PHP applications to optimize the process of file storage and retrieval.
Understanding S3 Buckets
An S3 bucket serves as a repository for objects, encompassing various data types such as files, images, videos, and more. Each object within S3 possesses a unique identifier known as its key, while buckets function as the highest-level namespace for organizing these objects. The scalability of S3 buckets is unparalleled, enabling the storage of an unlimited number of objects.
Setting up the Environment
Download the AWS SDK for PHP via composer
Then, run the following command
composer require aws/aws-sdk-php
Uploading files to the bucket
To upload a file to the S3 bucket, we use the putObject method provided by the S3 client. This method requires the bucket name, the object key (which is the path and name of the file in the bucket), and the file content. We can specify additional options such as the file's MIME type and any custom metadata we want to attach to the object.
Create a sample PHP file(e.g. testing.php) and use this code
<?php //Load autolaod require '/var/www/html/vendor/autoload.php'; use Aws\S3\S3Client; use Aws\S3\Exception\S3Exception;
$s3Client = new S3Client([ 'version' => 'latest', 'region' => 'ap-south-1', 'credentials' => [ 'key' => 'Your Access Key ID', 'secret' => 'Your secret access key' ] ]); // Send File into S3 Bucket. $bucket = 'Your Bucket Name'; $file_Path = "D:/test.jpg"; //Your Local path file $key = basename($file_Path);
try { $result = $s3Client->putObject([ 'Bucket' => $bucket, 'Key' => $key, 'Body' => fopen($file_Path, 'r'), 'StorageClass' => 'REDUCED_REDUNDANCY' ]); $msg = 'File has been uploaded'; } catch (Aws\S3\Exception\S3Exception $e) { echo $e->getMessage();die(); } ?>
Retrieving files from an S3 bucket
To retrieve a file from an S3 bucket, we use the getObject method provided by the S3 client. This method requires the bucket name and the object key of the file we want to download. It returns the file's content, which can then be saved locally or processed further within our PHP application.
<?php //Load autolaod require '/var/www/html/vendor/autoload.php'; use Aws\S3\S3Client; use Aws\S3\Exception\S3Exception;
// Instantiate an Amazon S3 client. $s3Client = new S3Client([ 'version' => 'latest', 'region' => 'ap-south-1', 'credentials' => [ 'key' => 'Your Access Key ID', 'secret' => 'Your secret access key' ] ]); $bucket = "Your Bucket Name"; try {
$key = "test.jpg";
$objects_assembles = $s3Client->getObject(array( 'Bucket' => $bucket, 'Key' => $key, 'command.response_body' => EntityBody::factory(fopen("/tmp/{$key}", 'w+')) ));
print_r($objects_assembles);exit; } catch (Aws\S3\Exception\S3Exception $e) { echo $e->getMessage();die(); }?>
Delete files from an S3 bucket
To delete a file from an S3 bucket, we use the deleteMatchingObjects method provided by the S3 client. This method requires the bucket name and the object key of the file we want to download.
