Since we're not formatting decimals with a specific precision, wouldn't the normal PHP string expansion work the same here and at line 295 saving us 2 function calls?

```php
$directory = "/tmp/images/{$dbname}/";
//and
$config = '/etc/s3cmd/sjc_prod.cfg'; //since this is being passed as a parameter to sprintf I guess than it should be a variable?
$cmd = "sudo /usr/bin/s3cmd -c {$config} sync s3://{$container}/images \"{$directory}\" --exclude \"/thumb/*\" --exclude \"/temp/*\"";  
```
