Description:
------------
The PHP documentation has led me to believe that "oci_connect() returns a connection identifier needed for most other OCI calls" (verbatim from the docs). For the sake of simplicity in this example, I just want to connect then close the connection. However, my call to oci_close() doesn't like what oci_connect() returned.....thinking it's a boolean value instead of the "resource" as shown at: http://us2.php.net/manual/en/function.oci-connect.php

I know it's actually talking to the server because it gives me a logon failure when I use an invalid username/password. 

Reproduce code:
---------------
#!/usr/local/bin/php
<?
$conn = oci_connect('username', 'password', '//server:1521/dbname') || die("Could not connect to Oracle database");
var_dump($conn);
oci_close($conn);
?>

Expected result:
----------------
to not get the warning I am seeing.

Actual result:
--------------
bool(true)

Warning: oci_close() expects parameter 1 to be resource, boolean given in /my/problem/script on line 5
