s3-bucket-stream-zip-php's Issues

how to save the zip file in local machine without sending it to client

Files inside the zip file have 0kb size

I just tested the library but is not working for me.

It downloaded a file called "name-of-zipfile-to-send.zip", it contains 2 files, but files are 0Kb size.

None of the files have data... any idea?

Note: My Bucket contains 2 files

accessing 500+ files from s3 not possible

@jmathai I am using your script for stream zip and provide download file to the end user. It works fine for 30 or more files but when it comes to large bunch of files to download it give error message

This site can’t be reached

Looks like fetching large number of files from S3 is not possible with the script. Please advise.

will it work with version 3 aws php sdk?

I want to implement functionality of download whole folder as zip from s3 bucket but it seems like it isn't gonna work with PHP v3 aws SDK.

curl_setopt(): supplied argument is not a valid File-Handle resource ^2.0

here is my code:

$params = [
                "key" => "myKey",
                "secret" => "mySecret",
                "region" => "ap-southeast-1",
                "bucket" => "myBuket",
                "prefix" => "571/low/"
            ];
$stream = new S3BucketStreamZip($params);
$stream->send('name-of-zipfile-to-send.zip');
I'm sure all params is valid as I had upload successfully to my bucket, but I have no idea why I got this error, maybe something wrong for me related with this code (/jmathai/s3-bucket-stream-zip-php/src/S3BucketStreamZip.php):
$fp = tmpfile();
$ch = curl_init($signedUrl);
curl_setopt($ch, CURLOPT_TIMEOUT, 120);
curl_setopt($ch, CURLOPT_FILE, $fp);  // <---- 
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_exec($ch);
 curl_close($ch);

Thanks,

Unable to composer install the package

Hi,
I am unable to composer install this because the package version of "aws/aws-sdk-php" is 2.8 and I already have 3.0.
Could you please update the package version here .

Thanks,

Want to run multiple zip download from for loop but closes tab after 1st zip download starts

How to download multiple zips from for-loop call
below code closes the browser tab when 1st zip download starts so that remaining loops cant work

i.e.
$RowImagesData = array() // in which multiple references are added.
$obj =& get_instance();
$obj->load->library('s3_stream');
$obj->load->library('aws_sdk');
$s3_dir= 'images/';
$bucketname= 'XYZ';

foreach ($RowImagesData as $RIKey => $RIValue)
{
$OrderId = $RIValue['reference']
$path = $s3_dir. $OrderId;
$files = $obj->aws_sdk->listObjects(array('Bucket' => $bucketname, 'MaxKeys' => 1000, 'Prefix' => $path))->getPath('Contents');
if(count($files) > 0)
{
$obj->s3_stream->download($bucketname,$path,$orderid);
}
else
{
echo "<script type='text/javascript'>alert('Order - $orderid does not exist');</script>";
}
}
