[PHP] OCILogin error message

[Dharmesh Goradia]

Hi,
       I'm having trouble with connection of Oracle. I have followed the
following steps

  1.I have installed oracle (client side) on my web server
  2.I have installed php, copied php.ini file into WinNt/System32
directory
  3.Uncommented extension = php_oci8.dll (even copied the php_oci8.dll
into WinNt/System32 directory and tried with that) 

   I'm getting the error message 
Fatal error: Call to undefined function: ocilogon()
