Thanks in advance.

I copied oci8 directory under 'ext' in php-4.2.3 ( an old version ) under 'ext' directory in php-4.3.2RC1 and I recompiled php. All work well. I hope this help you to understand the problem.

Excuse me for my english.
Thanks

This should be fixed now.

This bug has been fixed in CVS.

grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.
