Handling objects (again)

Hello to everyone, I'm manipulating objects in some scripts I've developed, and I've come across a doubt: I perform a query and do some checkings, but to perform this checkings I need to instantiate an object, and I really don't know how to do it without crashing theWeb Server. Let me give an example (I work in a Library and the example is directed to that): $dbConn->query('select nr_book from book_loan where cd_user = '.$cdUser); $nextRecord = $dbConn->nextRecord(); while ($nextRecord) { $book = new TBook($dbConn->field('NR_BOOK')); echo $book->getTitle().'<br>'; //how do I destroy the object here? $nextRecord = $dbConn->nextRecord(); } If I don't destroy the object the Web Server falls into some kind of deadlock and kills itself. And I didn't find a good explanation about how to do that in the PHP documentation in www.php.net I use Apache 2.0.54 as a Web Server and I use PHP 4.4.1 here at work. TIA, Marcos R.
