Try this:
This works for mysql:

 INSERT INTO ops (`numops`) VALUES ((SELECT LAST_INSERT_ID())+1);

This works for php:

mysql_query("INSERT INTO ops (`numops`) VALUES (0)");
mysql_query("UPDATE ops `numops` ='".mysql_insert_id()."' WHERE `id` = '".mysql_insert_id()."'");

Or

 mysql_query("INSERT INTO ops (`numops`) VALUES ('".mysql_insert_id()."')"); 
// this will only works if there is the same query executed before this.
