PHP's loadQuery() and saveQuery() are just methods that expose the
functionality of the mapserv CGI's "SAVEQUERY" function. My
understanding is as Adam wrote, that they save and load the contents of
the result cache, to allow you to maintain the results of a query
highlighted on the map when you browse after a query.

Someone mentioned in this thread that changing the layer order would
break the saved query, and yes, I believe that's true. It's up to the
application code to not prevent that from happening.
