Oracle database connection

Hi guys.

I'm trying to connect to an oracle database using Laravel, but for some reason, when i uncomment the extension=php_oci8_12c.dll from php.ini (I have it in xampp) i get the following error: The procedure entry poin OCIStmtGetNextResult could not be located in the dynamic link library OCI.dll.

I downloaded the instantclient, extracted it and then link to it in environment variables. Any idea how to fix this problem?

Thanks in advance xD
