It depends on what you want to secure.
If you want to secure the communication between the user-agent (browser) to your web server, you need to set up a certificate on the web server.
If you want to secure the communication between the web server (the DB client) and the MySQL server, you need to set up a certificate on the MySQL server.
In addition, you could make the MySQL client (your PHP script) use a client-certificate to authenticate to the MySQL server. This might not be necessary if MySQL username/password are considered enough.
