the ocifreestatment function doesn't actually free the Oracle cursor, these are only freed when the script exits.

While this isn't a problem when using PHP as a web page it is a problem if you have a command line script that has to perform thousands (or tens of thousands) of queries eventually the open_cursors limit is exceeded and all further queries fail.

The same appears to be true with connections.

what makes you belive it doesn't work?

please send me a short testcase that shows leakage of 
resources.

I have a long-running PHP script that eventually comes up with: 

Failed execution, error: ORA-00604: error occurred at recursive SQL level 2 ORA-01000: maximum open cursors exceeded.

I don't explicitly use any cursors in this script btw. In addition I found (via a web search) that someone else has been experiencing the same thing.

However, in response to your request I've been trying to build a test script to leak cursors and reproduce the problem, unfortunately, thus far, even deliberately leaking cursors is not producing it. :(

With the help of v$open_cursor I've tracked down the problem and it was a case of user error, my apologies for having taken up your time.
