s3 file to local system php - amazon-s3

how would I get the file from amazon s3 to local system using php.
I am trying to do this but its not working
$s3 = new AmazonS3("key 1", " acces pass");
$s3->getObject("Bucket/filename");
//write to local
$fp = fopen('/tmp/filename.mp4', 'w');
fpassthru($fp);
EDIT
I am trying to save the file to my local server from s3

As of 3.35.x verison AWS SDK -- the following snippet works with SaveAs.
Notice the buket name, key, and saveas with full path with file name.
$result = $s3->getObject(array(
'Bucket' => $bucket,
'Key' => $key,
'SaveAs' => $path . $model->file_name,
));

Check out the docs for getObject:
You need to either pass the remote file name as the 2nd param, then in the options set the value of 'fileDownload' to a file name or an OPEN file resource as a parameter there.
Example:
$s3->getObject('myBucket','myRemoteFile', array('fileDownload' => 'localFileName'));

When i download file programmatically from s3 bucket, It gives me error It looks like we don't support this file format

When I download file from s3 bucket, I am using aws-sdk for that, it downloads the files but when i open that file it says It looks like we don't support this file format, here is my full code of it, can anyone please check my code and help me why image is doesn't open the image, my wholde code is in PHP, It looks like small error but doesn't working for me
$bucket = '*****';
$keyname = '1560346461616.jpg';
$s3 = new S3Client([
'version' => 'latest',
'region' => '******',
'credentials' => [
'key' => '******',
'secret' => '******',
],
]);
$result = $s3->getObject([
'Bucket' => $bucket,
'Key' => $keyname,
]);
header("Content-Type: {$result['ContentType']}");
header('Content-Disposition: attachment; filename='.$keyname);
echo $result['Body'];
} catch (Exception $e) {
echo $e->getMessage() . PHP_EOL;
}
Check the content type of your .jpg file stored in s3. Ensure the metadata for this object says image/jpeg.I don't think it is related to the object you downloaded,maybe the download file was corrupted.

Uploading a file to S3 in laravel

I am using larvel 4.2 and I have got these libraries added in my vendor folder. aws-sdk-php and aws-sdk-php-laravel.
When I try to upload a file in s3 bucket, it uploads a file of 45B only and the content of that file is a string specifying file location on file system. $file object is legit and it has been constructed using $file = Input::file($field->element_name);
$s3 = App::make('aws')->get('s3');
$result = $s3->putObject(array(
'Bucket' => 'phxdevapp',
'Key' => $file_new_name,
'Body' => $file
));
Any pointers ?

reading a file from s3 bucket with laravel getting error

Im trying to get file from s3 bucket using getObject
$s3 = AWS::createClient('s3');
$file = $s3->getObject(array(
'Bucket' => 'hotel4cast',
'Key' => $path->path,
'SaveAs' => public_path()
));
I'm getting below error
Error executing
"GetObject" on "https://s3.amazonaws.com/mybucket/filename.xlsx";
AWS HTTP error: Unable to open /var/www/html/laravel/public/ using mode r+: fopen(/var/www/html/laravel/public/):
ailed to open stream: Is a directory
if i take SaveAs out and dump $file i get object of data, body, stream all that stuff but not sure what to do with that.
I have figured out, there is bug in aws sdk,
i was able to get file to save by storing path in var before calling getObject
$r = fopen(public_path() . '/myfile.xlsx', 'wb');
$s3 = AWS::createClient('s3');
$file = $s3->getObject(array(
'Bucket' => 'bucketname',
'Key' => $path->path,
'SaveAs' => $r
));
can you tell me that what exactly these equals too ? So, I can guide you accordingly.
$path->path = ???
public_path() = ???
Edited
your method params should be like this, you just passing the saveAs path but attaching the key name, So, add the keyname with saveAs path, it will be downloaded.
$s3 = AWS::createClient('s3');
$file = $s3->getObject(array(
'Bucket' => 'hotel4cast',
'Key' => $path->path,
'SaveAs' => public_path()."/filename.xlsx"
));
here are the examples of code, which I am using for uploading file and coping file
for uploading
$result = $this->S3->putObject([
'ACL' => 'public-read-write',
'Bucket' => 'xyz', // REQUIRED
'Key' => 'file.xlsx', // REQUIRED
'SourceFile' => public_path()."/xlsx/file.xlsx",
]);
for Coping from one bucket to another
$copy = $this->S3->copyObject(array(
'ACL' => 'public-read-write',
'Bucket' => 'xyz', // REQUIRED
'Key' => 'file.xlsx', // REQUIRED
'CopySource' => 'mybucketname/xlsx/file.xlsx,
));
but your file which is exists in s3 bucket should have permission to read. other wise it will give you error to saveAs, copy etc
here are multiple permissions, you can see here
'ACL' => 'private|public-read|public-read-write|authenticated-read|aws-exec-read|bucket-owner-read|bucket-owner-full-control',

How to manage database settings in Yii while running?

I want to let user manage database connection settings from website itself. I've thought that I would save db setting in a txt file and before every connection these would be read from this file first. Is it even possible?
I tried to use this in the main config file, but it does not work:
$myfile = Yii::app()->file->set('assets/settings.txt', true);
$array = explode("\r\n", $myfile->getContents());
$dblink = $array[0];
...
'db' => array(
'connectionString' => $dblink,

Amazon AWS S3 to Force Download Mp3 File instead of Stream It

I'm using Amazon S3 to put the mp3 file then allow our site visitor to download the mp3 from Amazon AWS. I use S3Fox to manage the file, everything seems working fine until recently we got many complaints from visitor that the mp3 was streamed via the browser instead of displaying browser save dialog.
I try for some mp3 and notice that for some mp3, the save dialog box is appear, and for some others they're streamed via browser. What can I do to force that the mp3 file will be downloaded instead of streamed via web browser....
Any help would be much appreciated.
Thanks
In order to do so you need to set the Content-Disposition header:
Content-disposition: attachment; filename=song.mp3
I don't think this is possible with S3Fox. You could use Bucket Explorer (not free) or write a script to upload the files.
Ok, it's been a long time since you ask this, but I had the same problem and I'd like to share my solution with the community, just in case someone else need to solve this thing. Of course, you can change Content-Type and Content-Disposition from the Amazon S3 Console, but the interesting thing is to do it programmatically.
The following code works fine for me:
require_once '../sdk-1.4.2.1/sdk.class.php';
// Instantiate the class
$s3 = new AmazonS3();
// Copy object over itself and modify headers
$response = $s3->copy_object(
array( // Source
'bucket' => 'your_bucket',
'filename' => 'Key/To/YourFile'
),
array( // Destination
'bucket' => 'your_bucket',
'filename' => 'Key/To/YourFile'
),
array( // Optional parameters
'headers' => array(
'Content-Type' => 'application/octet-stream',
'Content-Disposition' => 'attachment'
)
)
);
// Success?
var_dump($response->isOK());
Hope it can helps other struggling with the same trouble.
This ended up being my solution for force downloading files from AWS S3.
In safari the files were downloading as .html files until I stopped returning the readfile and just ran the function alone.
public function get_download($upload_id)
{
try {
$upload = Upload::find($upload_id);
if ($upload->deleted)
throw new Exception("This resource has been deleted.");
if ($upload->filename == '')
throw new Exception("No downloadable file found. Please email info#clouddueling.com for support.");
header("Content-Description: File Transfer");
header("Content-Type: application/octet-stream");
header("Content-Disposition: attachment; filename={$upload->uploaded_filename};");
readfile("https://s3.amazonaws.com/stackoverflow/uploads/" . $upload->filename);
exit;
} catch(Exception $e) {
return $e->getMessage();
}
}
In s3 management console window, right click and chose properties.
Click on metadata.
Click on add more metadata
Key: content-disposition
Value: attachment
Save. That's all.
