To "me at julez-edward dot be": while() doesn't "destroy" the query at all. Each result resource has an internal pointer that references the row being operated on. mysql_fetch_object increments that pointer, so that the next time, the next row will be returned. To solve this, use mysql_data_seek. To refine your example: <?php $all = @mysql_db_query($db,"SELECT * FROM person"); while ($item = @mysql_fetch_object($all)) { //do stuff. } mysql_data_seek($all, 0); // Returns the internal pointer to the first row of results. while ($item2 = @mysql_fetch_object($all)) { echo "Second while succesfully parsed."; //do other stuff. } ---- Manual Page -- http://www.php.net/manual/en/control-structures.while.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+52411 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+52411&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+52411&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+52411&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+52411&report=yes&reason=useless Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+52411&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+52411&report=yes Search -- http://master.php.net/manage/user-notes.php
