Same code done with ext/mssql functions works, though. Reproduce code: --------------- $db = new PDO('dblib:host=hostname;dbname=database', 'user', 'password'); $query = 'SELECT GETDATE()'; // NOW() on mysql for ($i = 0; $i < 10; $i++) { $stmt = $db->query($query); // new statement $stmt->fetch(); // actual data $stmt->fetch(); // false; end of resultset $stmt->closeCursor(); // this should at least free it, right? $stmt = null; // being paranoid here echo memory_get_usage() . "\n"; } Expected result: ---------------- 54152 54152 54152 54152 54152 54152 54152 54152 54152 54152 Actual result: -------------- 54152 54252 54292 54332 54372 54412 54452 54492 54532 54572 ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=40121&edit=1
