Question

Is there a more efficient way to list files from a bucket in Amazon S3 and also extract the meta data for each of those files? I’m using the AWS PHP SDK.

if ($paths = $s3->get_object_list('my-bucket')) {
    foreach($paths AS $path) {
        $meta = $s3->get_object_metadata('my-bucket', $path);
        echo $path . ' was modified on ' . $meta['LastModified'] . '<br />';
    }
}

At the moment I need to run get_object_list() to list all the files and then get_object_metadata() for each file to get its meta data.

If I have 100 files in my bucket, it makes 101 calls to get this data. It would be good if it’s possible to do it in 1 call.

E.g:

if ($paths = $s3->get_object_list('my-bucket')) {
    foreach($paths AS $path) {
        echo $path['FileName'] . ' was modified on ' . $path['LastModified'] . '<br />';
    }
}

Answer 1

I ended up using the list_objects function which pulled out the LastModified meta I required.

All in one call 🙂
