Getting time of a postgresql-request

Dear users,

I try to optimize the time of my Postgresql-requests, but for that, the first step,
I of course need to get that time.

I know that with:

EXPLAIN ANALYSE SELECT bundesland from
 bundesland WHERE ST_Contains(the_geom, $punktgeometrie_start) AND
 ST_Contains(the_geom, $punktgeometrie_ende)

I can get that time on command line.

But I would like to get it in a php-script, like

$timerequest_result=pg_result($timerequest,0);

(well, that does not work).

I wonder: Is there another way to get the time a request needs?
How do you handle this?

Thank you very much, Kai
