Problem PHP Oracle - Instant Client

Question

Hi,
i have been trying to resolve this issue but im not really sure what i need to do, could someone help me?
Warning: oci_connect() [function.oci-connect]: OCIEnvNlsCreate() failed. There is something wrong with your system - please check that PATH includes the directory with Oracle Instant Client libraries
Im getting this error when i try to connect to a Oracle database via PHP.
My host is Windows, Oracle instant client is on C:\instantclient_11_2 and added on PATH Variables.
I think there are missing some oracle variables on my phpinfo(), below:

Answer 1

Your PATH includes "C:\instantclient_11_2;O:\ora11202". This hints that you have multiple versions of Oracle installed, which is common cause of issues.
Do you need Instant Client?  If you already have an Oracle DB you don't really need Instant Client unless you have a particular version requirement.
