I'm not a php expert but have some insights about the python mapscript.

So here is my answer ;-)

queryByPoint returns a MS_SUCCESS in case of a query giving results and
MS_FAILURE otherwise. You can't have much details about the failure : is
it an empty query ? or a bad formatted query ?

If MS_SUCCESS, you can access the resultset using layer.getResults()
