Which host do I need to fill in the database connection? So I have made a local Drupal site and now I'm moving it to my webhost. In the database connection array: 

$databases['default']['default'] = array(
  'driver' =&gt; 'mysql',
  'database' =&gt; 'drupaldb',
  'username' =&gt; 'username',
  'password' =&gt; 'secret',
  'host' =&gt; 'localhost',
);


So I filled in all my credentials (driver, database, username,...) but what do I need to fill in after 'host'? Can I just leave it 'localhost' or do I need to fill in the host of my webhosting?
It will depend on your hosting setup and where the DB is located. The host value can be:


A reachable hostname where the PHP code is running (e.g. localhost for your local server)
An IP address (e.g. 127.0.0.1, the ip address normally used for localhost), 
A fully qualified domain name (e.g. my-data-base-host.example.com)


Consult your hosting provider on retrieving your DB host connection credentials.
