Win2K, Apache, PHP and Oracle8i

I have problem. I'm Using a Win2K server with oracle8i, php4 and Apache. Whenever i use OCILogon the php file comes up with the following error : Fatal error: Call to unsupported or undefined function ocilogon() in i:\apache\test.php on line 8 Line 8 looks like this : $c1 = OCILogon("scott","tiger",$db); (not the actual user/password of course) I installed a dll called php_oci8.dll that i got from http://download.swwwing.com/php4/modules/ using "extension=php_oci8.dll". This did not work. Then i tried installing PHP3 which apparently has a oci module included called php3_oci80.dll. Including this did not help either. I also tried using the older oracle functions, namely Ora_Logon. This came up with the same error as above, only it said ora_logon instead of ocilogon. Does anyone know how to get Oracle8i support in a Windows PHP? With Kind Regards Allan K
