How to connect Oracle to Yii2 and not hang yourself?

Question

Oracle

I'm getting an error when using oracle db

spoiler

Caused by: PDOException
could not find driver

What I did:
I downloaded Instant Client version 11.1.0.7.0
Client Oracle 11g 32 bit, I already have it installed. Everything works fine and I see the server base and work with it.
Registered global variables

Even installed the 32-bit version of php and included it in php.ini

extension = oci8_12c
extension = pdo_oci

EVERYTHING still does not see the driver and gives the same error. How else can you solve the problem? The official php documentation doesn't help https://www.php.net/manual/en/oci8.installation.php

I figured out the connection, it remains to teach him to see TNS-ki. But for people who will face a similar problem, I will sign:
1) You should have only 1 oci driver in global variables, and not two as I have above in the screenshots (1 driver from Oracle Client, another from instant client). If you have the oracle client installed, you don't need to install any instant client.
2) Give your server access to global Windows variables.
3) In php.ini, uncomment Oci (You should have 1 axis uncommented in total)
4) Catch the following error related to TNS) (Fixed, indicated the correct format for accessing TNS https://www.php.net/manual/en/ ref.pdo-oci.connecti...
