Using PHP to upload to Amazon S3 - php

Question

I've spent the last few hours following tutorials for implementing file uploads to Amazon S3 using php. I uploaded the most recent version of Donovan Schönknecht's S3 class to my server (as S3.php) and I am trying to use the following code to test upload capability. I know this code will work because I've seen numerous examples in action.
<?php
require('S3.php');
$s3 = new S3('KEY', 'SECRET KEY');
//insert into s3
$new_name = time() . '.txt';
S3::putObject(
'upload-me.txt',
'bucketName',
$new_name,
S3::ACL_PUBLIC_READ,
array(),
array(),
S3::STORAGE_CLASS_RRS
);
?>
I get an error 500 server error when I attempt to load this page. Additionally, every other reputable tutorial of this nature has given me the same error 500.
I verified that my key and secret key are valid by connecting to S3 with Cyberduck.
Does anyone have a clue as to what I could be doing incorrectly?
Thanks,
Sean

Answer 1

As it turns out, I was missing the cURL extension for PHP and this was causing an issue as the S3 class I was using required the use of cURL. All is working now.

Answer 2

You should also consider using the official AWS SDK for PHP. Examples for using S3 with the SDK can be found in their S3 user guide.

Answer 3

You can download most recent version of Amazon PHP SDK by running following composer command
composer require aws/aws-sdk-php
Further configuration to upload file on Amazon s3 are following
// Include the SDK using the Composer autoloader
require 'vendor/autoload.php';
use Aws\S3\S3Client;
use Aws\S3\Exception\S3Exception;
// Set Amazon s3 credentials
$client = S3Client::factory(
array(
'key' => "your-key",
'secret' => "your secret key"
)
);
try {
$client->putObject(array(
'Bucket'=>'your-bucket-name',
'Key' => 'your-filepath-in-bucket',
'SourceFile' => 'source-filename-with-path',
'StorageClass' => 'REDUCED_REDUNDANCY'
));
} catch (S3Exception $e) {
// Catch an S3 specific exception.
echo $e->getMessage();
}

Following example worked for me:
<?php
use Aws\S3\S3Client;
use Aws\S3\Exception\S3Exception;
$client = S3Client::factory([
'version' => 'latest',
'region' => 'us-west-1',
'credentials' => [
'key' => "<scret-key>",
'secret' => "<my-secret>"
]
]);
try {
$client->putObject([
'Bucket' =>'<my-bucket-name>',
'Key' => '<file-name>',
'SourceFile' => '<file-path-on-server>', // like /var/www/vhosts/mysite/file.csv
'ACL' => 'public-read',
]);
} catch (S3Exception $e) {
// Catch an S3 specific exception.
echo $e->getMessage();
}

Use this one to Upload Images using a form and it's working Fine for me
you may try using it with your code
$name = $_FILES['photo']['name'];
$size = $_FILES['photo']['size'];
$tmp = $_FILES['photo']['tmp_name'];
//////Upload Process
// Bucket Name
$bucket = 'bucket-name';
require_once('S3.php');
//AWS access info
$awsAccessKey = 'awsAccessKey';
$awsSecretKey = 'awsSecretKey';
//instantiate the class
$s3 = new S3($awsAccessKey, $awsSecretKey);
$s3->putBucket($bucket, S3::ACL_PUBLIC_READ);
//Rename image name.
$actual_image_name = time();
//Upload to S3
if($s3->putObjectFile($tmp, $bucket , $actual_image_name, S3::ACL_PUBLIC_READ) )
{
$image='http://'.$bucket.'.s3.amazonaws.com/'.$actual_image_name;
}else{
echo 'error uploading to S3 Amazon';
}

I never found a updated Script with Amazons latest sdk. i have made it by myself. it woks as a php commandline interpreter script. give it a try :

Answer 7

I'm not familiar with S3 API, but i used it as the storage with https://github.com/KnpLabs/Gaufrette. Gaufrette is a library that provides pretty nice abstraction layer above S3 and other file services/systems.

Answer 8

Here is sample code to upload images on Amazon S3.
// Bucket Name
$bucket="BucketName";
if (!class_exists('S3'))require_once('S3.php');
//AWS access info
if (!defined('awsAccessKey')) define('awsAccessKey', 'ACCESS_KEY');
if (!defined('awsSecretKey')) define('awsSecretKey', 'ACCESS_Secret_KEY');
$s3 = new S3(awsAccessKey, awsSecretKey);
$s3->putBucket($bucket, S3::ACL_PUBLIC_READ);
if($s3->putObjectFile($tmp, $bucket , $image_name_actual,S3::ACL_PUBLIC_READ) )
{
$message = "S3 Upload Successful.";
$s3file='http://'.$bucket.'.s3.amazonaws.com/'.$actual_image_name;
echo "<img src='$s3file'/>";
echo 'S3 File URL:'.$s3file;
}
else{
$message = "S3 Upload Fail.";
}
}

Below is the best solution. Its using multipart upload.Make Sure to install Aws SDK for PHP before using
require 'vendor/autoload.php';
use Aws\S3\S3Client;
use Aws\Exception\AwsException;
use Aws\S3\MultipartUploader;
use Aws\Exception\MultipartUploadException;
try {
$s3Client = new S3Client([
'version' => 'latest',
'region' => 'us-east-1',
'credentials' => [
'key' => 'AKIAUMIZJR5U5IO7M3',
'secret' => 'BmcA3vFso1bc/9GVK7nHJtFk0tQL6Vi5OoMySO',
],
]);
// Use multipart upload
$source = 'https://b8q9h6y2.stackpathcdn.com/wp-content/uploads/2016/08/banner-for-website-4.png';
$uploader = new MultipartUploader($s3Client, $source, [
'bucket' => 'videofilessandeep',
'key' => 'my-file.png',
'ACL' => 'public-read',
]);
try {
$result = $uploader->upload();
echo "Upload complete: {$result['ObjectURL']}\n";
} catch (MultipartUploadException $e) {
echo $e->getMessage() . "\n";
}
} catch (Exception $e) {
print_r($e);
}
