cx_Oracle.DatabaseError: DPI-1047: Cannot locate a 64-bit Oracle Client library: "failed to get message for Windows Error 126". See https://cx-oracle.readthedocs.io/en/latest/user_guide/installation.html for help
Code:
import cx_Oracle
dsn_tns = cx_Oracle.makedsn('192.168.1.217', '1521', service_name='xx')
conn = cx_Oracle.connect('xx','xx', dsn_tns,'UTF-8')

Here are the cx_Oracle Windows installation instructions , which you probably found from the error message you quoted.
I will assume (i) you actually have 64-bit Oracle client libraries 11g or later, and also (ii) have the required VS Redistributable as mentioned in the install instructions. Then a simple thing to try is to add this to the top of your script:
cx_Oracle.init_oracle_client(lib_dir=r"C:\oracle\instantclient_19_6")
Use the actual path to your client libraries.
PHP may be 32-bit and using 32-bit Oracle libraries. If so, because you have a 64-bit Python, then you will need to install 64-bit Instant Client or install 32-bit Python.
