php3.0.16 oracle connectivity problem on IIS 5.0 / win 2000

hi all greetings please help me - badly in need of ur support.... i am not able to connect to oracle 8.0 server. the error what i get is "Fatal error: Call to unsupported or undefined function ocilogon() in c:\inetpub\wwwroot\php\ereg\testorcon.php on line 8" i have php 3.0.16 configured to IIS 5 on win 2000 professional, oracle8.0 client . i have the php3_oci80.dll, php3_oci73.dll in my c:\php directory. the extension entries are uncommented for auto loading the modules in php3.ini situated in c:\winnt directory. i have added c:\php in my PATH variable. i faced the same problem with php4 too. the extract of php4.0.0-win32.zip does not contain any dll targetting oracle (for example php3_oci80.dll in php 3). why is it so? is there any other dll satisfying the purpose? waiting for a helpful reply deepaks ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
