Description:
------------
I am trying to get a php script to talk to a remote oracle
database. I have successfully built your extension and
set it up in the php config; a phpinfo() call shows the
extension loading, as does php -m. I was able to run tests/connect.phpt successfully.

However I cannot get connections to the database to work,
apparently because I lack the pdo_oci module. The exact
error messsage is:
  exception 'PDOException': could not find driver in <path to code module>.

I am trying to understand whether the PDO_OCI module is still needed. This is unclear from the documentation I have been able to review. My confusion would be less if there
was some brief explanation of the relationship between the oci8 and pdo_oci extensions in the README file.

I attempted to build the pdo_oci-1.0 extension but it fails
because my version of instantclient (11.1.0.1) is not supported; no updates of this have been made since 2005 so there seems little point in filing a bug on it... But feel free to reassign this if you think the report will get a response.

To clarify the issue I was having - I was trying to get code
that used the PDO API to access the database. This is the
part that was failing; the oci_* functions seem to work ok.

The suggested patch below might help explain what I am on about.

This bug has been fixed in CVS.

In case this was a documentation problem, the fix will show up at the
end of next Sunday (CET) on pecl.php.net.

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