WampServer

I have been using WAMP on this computer for 5+ years, but never updated the version.
Last week I had to rebuild this machine.
I downloaded and installed new wamp server.
I can no longer connect to existing Oracle database(s) on other servers.

Apache/2.4.23 (Win64) PHP/5.6.25 - Port defined for Apache: 80
I have access to the regular www\index.php file, and it outputs all the "normal" stuff, but nothing like oci shows in the loaded extensions.
I have access to phymyadmin

php.ini:
extension=php_oci8_12c.dll ; Use with Oracle Database 12c Instant Client
extension=php_pdo_oci.dll
and I've enabled every oci8. in the [OCI8] section


PHP output:
Fatal error: Call to undefined function oci_connect() in C:\wamp64\www\...

I can't find the phrase "not a valid Win32 application" when I search on this site.
Nor do I find any results for just "oci" when searching on this site (without the quotes).


I'm not sure what to do.
Any help would be appreciated.
Thanks in advance.

Hi

Did you re-install the Oracle Client on this PC?

Did you install the 63bit version of the Oracle Client?

Actually, is there a 64bit Oracle Client?

Read The Manuals Apache -- MySQL -- PHP -- phpMyAdmin
Get your Apache/MySQL/mariaDB/PHP ADDONs here from the WAMPServer alternate Repo

I haven't used Oracle client before, but yes, I did install the latest version of oracle client and got the same results, I restarted the computer just to be sure that the install and path "took" but no joy.
