How to delete from S3 - php

Question

I have a PHP file upload script for putting documents onto S3, so far the User can delete the file from the SQL list but not from S3 directly. Is they a simple way I can add the delete from S3 into the same code as below
The rest of the php script includes the s3.php if that helps
$bucket = 'files';
$path = 'file/'; // Can be empty ''
if (isset($_GET['id']))
{
$id = $_GET['id'];
$path .= 'File'.$id.'/';
if (isset($_GET['action']))
{
$action = $_GET['action'];
if ($action = "deleteFile")
{
$Fileid = $_GET['Fileid'];
$query = "DELETE FROM amazon_upload WHERE Upload_File_Id='".$Fileid."'";
$result = mysql_query($query);
if (!$result)
{
die ("could not query database: <br />".mysql_error());
}
$locationHeader = "Location: http://www.website.com/upload.php?id=".$id;
header($locationHeader);
}
}
}

Answer 1

this works well
$s3 = new AmazonS3();
$bucket = 'velobucket';
$folder = 'mydirectory/';
$response = $s3->get_object_list($bucket, array(
'prefix' => $folder
));
foreach ($response as $v) {
$s3->delete_object($bucket, $v);
}

Try With
unlink()
E.G
$file = "test.txt";
if (!unlink($file))
{
echo ("Error deleting $file");
}
else
{
echo ("Deleted $file");
}
