All: I'm running PHP in ISAPI mode with IIS accessing (or attempting to access) an Oracle 9i database on a RedHat box. Here are the versions of everything: Web Server: IIS v5.1 PHP: 5.2.5 Database: ORACLE v9i-R2 I am attempting to load a page with the following code: //Database credentials $username = "MyUser"; $passwd = "MyPassword"; $db="DBName"; //Return the database connection OCILogon($username, $passwd, $db); I receive an error stating, "Fatal error: Call to undefined function OCILogon() in C:\Documents and Settings\afortuno\My Documents\Dev\DBAIntranet\ghr_resources\transaction_report\adam.php on line 7" I'm able to use SQL Plus to login to the database I'm interested in. This gives me the impression that my credentials are not the problem; however, the plumbing between PHP and Oracle is the culprit. I initially had problems loading the OCI extension DLL. I resolved the issue by installing the Oracle 10g instant client. Here are the steps I followed as part of that process: (1) Download Oracle Instant Client Package Basic (v10.2.0.4) for Win32 http://www.oracle.com/technology/software/tech/oci/instantclient/htdocs/ winsoft.html (2) Unzip the contents downloaded zip-file. (3) Move the folder to the "C:\Oracle" directory. (4) Add the new folder (C:\oracle\ora102ic) to the PATH. (5) Restart IIS (e.g., C:\> iisreset). The error message couldn't be more vague, and I'm not experienced enough with Oracle, IIS, or PHP to know where to turn for more insight. Any help would be appreciated. Cheers, Adam
