I'd just convert spaces to an underscore. Or use a regex to matching anything not alphanumeric in the name and reject it if necessary. $safe_name = str_replace(' ','_',$name); or if(preg_match('/[^0-9a-z_-]/i',$name)) { echo 'bad name'; } else { echo 'good name'; } There may be a bug in the unlink function if you can't delete files with a space. You can do it from the command line if you place the name within quotes. Check out the PHP Bugs page to see if there's anyone reporting/working on this... ---John Holmes...
