This is a quick wrapper around an S3 class by Donovan Schonknecht that will recursively upload your files in a subdirectory to an S3 bucket, applying Cache Control control headers as it goes.

The original intent was to have a quick way to sync images on a development machine with a live S3 bucket that was serving images on a site, without having to use any crappy third-party software. This was spawned out of the need for a simple uploader that actually works. So far it's been great.

<?
	// quick config
	$bucket			=	'your.bucket.com';
	$start_folder	=	'images';

	// settings
	error_reporting(E_ALL);
	ini_set('display_errors', 1);
	ini_set('max_execution_time', 3600);

	// include S3 class
	include 'S3.php';
	$s3	=	new S3('[your key]', '[your secret]', false);

	// get list of files. if you don't want a subdirectory, just change this line to not need one. hopefully you know PHP...
	$files	=	recurse(array(), $start_folder);

	// loop over files and upload
	for($i = 0, $n = count($files); $i < $n; $i++)
	{
		$ext	=	preg_replace('/.*\./', '', $files[$i]);
		$type	=	'image/jpeg';
		if($ext == 'jpg')
		{
			$type	=	'image/jpeg';
		}
		else if($ext == 'gif')
		{
			$type	=	'image/gif';
		}
		else if($ext == 'png')
		{
			$type	=	'image/png';
		}

		if(
			!$s3->putObject(
				$s3->inputFile($files[$i]),
				$bucket,
				$files[$i],
				S3::ACL_PUBLIC_READ,
				array(),
				array('Cache-Control' => 'max-age=31536000', 'Content-Type' => $type)
			)
		)
		{
			echo '<span style="color:green;">Failed: upload of '. $files[$i] . '';
		}
		else
		{
			echo '<span style="color:green;">Succeeded: upload of '. $files[$i] .'';
			unlink($files[$i]);
		}
	}

	function recurse($files, $dir)
	{
		$d	=	scandir($dir);

		for($i = 0, $n = count($d); $i < $n; $i++)
		{
			if(!preg_match('/^\./', $d[$i]))
			{
				if(is_dir($dir . '/' . $d[$i]))
				{
					$files	=	recurse($files, $dir . '/' . $d[$i]);
				}
				else
				{
					$files[]	=	$dir . '/' . $d[$i];
				}
			}
		}

		return $files;
	}
?>

Enjoy.
