Description:
------------
Username (schema name), password and database (SID) in Oracle are always case-insensitive. However, OCI8 PECL package (and extension shipped with PHP distribution as well) does not take this into account and creates new connection if the same credential or database was given in changed case.

Please see a side note from the following bug:

http://bugs.php.net/bug.php?id=22674

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

ociinternaldebug(1);

$conn1 = ociplogon("same_user", "same_pass", "same_sid");
$conn2 = ociplogon("SAME_USER", "same_pass", "same_sid");

?>

Expected result:
----------------
There should be only one connection made to the database, i.e. it should print something like this:

OCI8 DEBUG: OCINlsEnvironmentVariableGet at (/tmp/tmpdFzG1r/oci8-1.1.1/oci8.c:923)

OCI8 DEBUG: OCITransRollback at (/tmp/tmpdFzG1r/oci8-1.1.1/oci8.c:1313) 

Actual result:
--------------
There are actually two connections made to the server. It is visible both from the OCI8 debug info as well as executing "select machine,process,username,status from v$session order by process" and looking for the particular Apache child.

Here is a dump from OCI8 debug info (two calls to OCISessionBegin proves it):
