SQL queries from an external DB in WordPress
<p>Actually I have a php website in my hosting. Now I am personalizing a Wordpress theme to replace it. It's all ok for now, but the old website has a built in function to connect to another database with a token. This connection is only to get some data.</p>

<p>Can you tell me how to implement this in my new wordpress theme?<br>
Did a wordpress plugin exists for this?</p>

<p>Thanks</p>
