Please consult the perl documentation located at https://perldoc.perl.org/.
The following example connects to the database “your_database_name” with the username “your_mysql_user” and password “your_password”. You will need to substitute these values for your actual database, username, and password you have set up in your hosting control panel (cPanel). If you have not already prepared a MySQL user and database in cPanel, please see the following instructions.
$mysql_server = "localhost";
$mysql_db = "your_database_name";
$mysql_user = "your_mysql_user";
$mysql_password = "your_password";
$dbh = DBI->connect("DBI:mysql:database=$mysql_db;host=$mysql_server", $mysql_user, $mysql_password, {'RaiseError' => 1});
