My website issues a SQLSTATE[HY000]  Unknown database 'xxxxxx' even after I have imported the database.
I am new to digital ocean, but have recently uploaded a website using the LAMP stack. The website is working fine, however I have an html form on a page that sends the data to a MySQL database. I imported the the database following this tutorial “How to Import and Export Databases in MySQL or MariaDB (https://www.digitalocean.com/community/tutorials/how-to-import-and-export-databases-in-mysql-or-mariadb)”.
When I check for the database in the MySQL interface in terminal through “SHOW DATABASES;”, I see that the database has been imported. I checked phpmyadmin and see that the tables have all been correctly configured. The error still occurs and it seems like my website/droplet is still unknown issuing the SQLSTATE[HY000]  Unknown database ‘xxxxxx’ error.
I use a PHP connection via PDO if that helps.
