Description:
------------
Please read attentively and help us if possible! 

We search for answer for this trouble through all forum and enythere in the internet but have not got it yet!
We have done all possible measures (different software and hardware configurations), but bug is still alive!

We have installed PHP as sapi on IIS (we have tried to use 5.0, 6.0 versions of IIS under Windows 2000 Advanced Server and Windows Server 2003 Enterprise).
We have Oracle Client 9.2.0.1.0 Enterprise edition.
We use PHP v4.3.7 (we have tried to use from v4.2.3 .... to v4.3.7).

With using of Oracle Client 9.0.1.1.1 all work properly.

Such kind of problem was discussed on the bug-forum, but there was no correct answer.

We have read following reports before we writing it:

and etc.

Reproduce code:
---------------
<?

$login    = "USERNAME";
$password = "********";
$db       = "DATABASE";
$connection = OCIPLogon($login, $password, $db);

if ( $connection ) print 'ok...';

?>

Expected result:
----------------
ok...

Actual result:
--------------
We get this:

IIS message: Unknown(): Unable to load dynamic library 'c:\php\extensions\php_oci8.dll' - Access is denied.

PHP message: Fatal error: Call to undefined function: ociplogon() in c:\inetpub\wwwroot\index.php on line 6

In console we get: 'ok...'.

Pay attention to "Access is denied" message.
Seems you have some problem with access privileges (maybe IIS can't open OCI libs or something like that).

[2004-07-07 15:35 UTC] support at gis dot tusur dot ru

This couldn't be an access privileges problem, because we use Oracle Client 9.0.1.1.1 before. And it works properly.

And now we switch between two Oracle cliens using Oracle Home Selector. But we must use only 9.2.0.1.0 in our project.

[2004-07-07 15:43 UTC] tony2001@php.net

Make sure ORACLE_HOME environment variable is visible to IIS (use phpinfo()) and points to the right dir.
Try to install new (9.2) Oracle Client on a clean server and try again if nothing helps.

This could be a problem of your upgrade tool.

We have tried all your recommendations, but haven't got correct result - our system still don't work properly!

[2004-07-08 11:13 UTC] sniper@php.net

Please ask installation support questions on an appropriate mailing list. This is a bug system and this is not a bug.

[2004-07-08 11:48 UTC] support at gis dot tusur dot ru

And what if this is not an IIS bug, but PHP, wich not currently compatible 
with IIS and Oracle 9.2 ??
How you may be shure, that your PHP product works fine under Oracle 9.2 
and IIS?
Still, that problem not solved, even after 2 year since that 
http://bugs.php.net/bug.php?id=20022 bug report.

In that case - just stop declaring that PHP supports Oracle 9.2 + ISS, at least until you'll test compability 
of your sofware in same configuration.

[2004-07-08 11:55 UTC] sniper@php.net

It doesn't say anywhere that we support IIS..Please read the docs.

>Is 9i ( 9.2.0.1.0 ) supported ?
yes

You should declare in documentation that PHP v4.* + IIS v* + Oracle 9.2/10g Client couldn't work together.

Only bugs that are actually fixed should have the status 'Closed'.
