note 39004 added to function.mysql-free-result

Is there a way to prevent php from giving the warning mentioned below, by checking what my query returned (result set or resource)? Checking whenever or not a query was run is easy: function close() { if ($this->result != null) mysql_free_result($this->result)); mysql_close($this->link); } ---- Manual Page -- http://www.php.net/manual/en/function.mysql-free-result.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+39004 Delete -- http://master.php.net/manage/user-notes.php?action=delete+39004&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+39004&report=yes Search -- http://master.php.net/manage/user-notes.php
