note 21063 added to function.fwrite

$fd = fopen("wotd.txt", "w") || die ("Can't create the file wotd.txt"); $input = "testing\\n"; if(fwrite($fd, $input) == -1) { die ("Can't write to file wotd.txt"); } fflush($fd); fclose($fd) || die ("Can't close the file wotd.txt"); My problem is that this error: Supplied argument is not a valid File-Handle resource appears in fwrite, fflush, fclose commands, but if $fd is not valid then I must have failed opening the file at the first line and see the indicated error message, but in my case this error message can't be found anywhere. What's wrong with this piece of code. Thank you for your helps. -- http://www.php.net/manual/en/function.fwrite.php http://master.php.net/manage/user-notes.php?action=edit+21063 http://master.php.net/manage/user-notes.php?action=delete+21063 http://master.php.net/manage/user-notes.php?action=reject+21063
