Hello,
I have been reading docs and many are telling that persistent connections
are kept open indefinitely. But I found in PHP docs that it will not close
after script execution like requesting a page; so should it close after
the request is over?
So when exactly a persistent connection should close?
Please advice.

Nibin.

A persistent connection is closed when the PHP process ends, or it gets
disconnected by the server-side or due to a network error. Attempting to
explicitly close a persistent connection will do nothing without complaining.

Thank you for the quick response Stuart...one more doubt..at
http://php.net/manual/en/features.persistent-connections.php they states
=========
This means that when the same client makes a second request to the server,
it may be served by a different child process than the first time. When
opening a persistent connection, every following page requesting SQL
services can reuse the same established connection to the SQL server
=========
Is the persistent connection pool is re-used between apache child
processes ?

No, connections are not shared between PHP processes. Nothing is shared between
PHP processes.

That wasn't a bitter rant. You haven't seen me bitter. :-) That was
"tough love" to the OP. I don't see a reason to pussyfoot around the
original question, which is one that comes up about once a month. The
answer is always the same: How much is your time worth?
Basic math...
Life: finite
Time: infinite
finite / infinite = 0
*sniffle*
Oh wait... you meant in the smaller scheme of things >:)
Cheers,
Rob.
