如何使用 PHP pdo_oci 扩展连接到 Oracle 19c

Question

How I can connect to Oracle 19c database with PHP pdo_oci extension on the Windows?

I have installed Oracle Instant Client 19.0.0, PHP 7.4.4 and Apache 2.4. Oracle database is in the other server.

I get an error "TNS protocol adapter error" when I want connect with PDO.

Connection via sqlplus is successful in the command line.

Answer 1

Did you configure your tnsnames.ora? If not you should create a folder inside the root of your instant client like so:

C:\instantclient_19_9\network\admin

Inside of that folder you should have a file called

tnsnames.ora

This file must contain your connection data

    test = 
  (DESCRIPTION =
    (ADDRESS = (PROTOCOL = TCP)(HOST = server_name_or_ip_address)(PORT = 1521))
    (CONNECT_DATA =
      (SERVER = DEDICATED)
      (SERVICE_NAME = test)
    )
  )
