So what if $fp is there and pointing to a closed file? There is no difference between that and something like: $fp = fopen(); fclose($fp); The $fp variable still exists and has a value, but the file is closed. How is that a problem? The problem in your pdf_close() function was that you ended up closing the file but not removing the file pointer from PHP's list of open files. That meant that when someone called fclose() on it specifically, or when PHP tried to clean up after you, it would try to fclose() a file that was already closed. -Rasmus -- PHP Development Mailing List http://www.php.net/ To unsubscribe send an empty message to php-dev-unsubscribe@lists.php.net For help: php-dev-help@lists.php.net
