Description:
------------
Startup errors when using PDO_OCI8 extension.

Reproduce code:
---------------
Install PHP 4.2.3

Select the following extensions to include in the install:

OCI8
PDO
PDO_OCI8

Turn on display_startup_errors in php.ini.

The following errors are displayed on Apache start up:

PHP Startup: Invalid library (maybe not a PHP library) 'php_pdo_oci8.dll'
PHP Startup: Invalid library (maybe not a PHP library) 'php_pdo_oci8.dll'

phpinfo() says the following PDO libraries are loaded

PDO
PDO support	enabled
PDO drivers 	oci

PDO_OCI
PDO Driver for OCI 8 and later	enabled

Run a small Oracle 10g PDO script. This is the script I used against and Oracle Database XE (10.2) database:

<?php

print_r(PDO::getAvailableDrivers());

  $dbh = new PDO('oci:dbname=//localhost/XE', 'hr', 'hr');
  $s = $dbh->prepare("select city from locations");
  $s->execute();
  while ($r = $s->fetch(PDO::FETCH_ASSOC)) {
    echo $r['CITY'] . "<br>";
  }
  $dbh = null;    // release the connection
?>

This script works, so PDO is actually installed and okay.

Here is the startup error in the Apache error log:

The files in my C:\Program Files\PHP\ext folder are:

php_oci8.dll
php_pdo.dll
php_pdo_oci8.dll
php_pdo_oci.dll

The entries in my php.ini are:

[PHP_OCI8]
extension=php_oci8.dll
[PHP_PDO]
extension=php_pdo.dll
[PHP_PDO_OCI]
extension=php_pdo_oci.dll
[PHP_PDO_OCI8]
extension=php_pdo_oci8.dll

Expected result:
----------------
No startup errors.

Actual result:
--------------
The following errors are displayed on Apache start up:

PHP Startup: Invalid library (maybe not a PHP library) 'php_pdo_oci8.dll'
PHP Startup: Invalid library (maybe not a PHP library) 'php_pdo_oci8.dll'
