This is happening because your $subject = mysql_query("SELECT * FROM deltimes WHERE state=1  AND ( value=CURDATE() ) "); returned FALSE due to the query failing, use mysql_error() to find out the error.

Usually do mysql_query() or die (mysql_error()) to ensure the code doesn't continue after an error.
