To connect to an external database in WordPress, you need to follow these steps:

1. Locate your WordPress installation on your server.
2. Find and open the wp-config.php file in the root folder of your WordPress installation.
3. Look for the lines that define database connection settings. They should look like this: define('DB_NAME', 'database_name'); define('DB_USER', 'username'); define('DB_PASSWORD', 'password'); define('DB_HOST', 'localhost');
4. Replace the existing database connection settings with the details of your external database. For example: define('DB_NAME', 'external_db_name'); define('DB_USER', 'external_db_username'); define('DB_PASSWORD', 'external_db_password'); define('DB_HOST', 'external_db_host'); Note: You will need to use the correct values provided by your hosting provider or administrator for the external database name, username, password, and host.
5. Save the wp-config.php file.

After making these changes, WordPress will use the new connection settings to connect to your external database.
