Is it advisable to automatically detect and react to multiple databases on a server in PHP, or is manual configuration preferred?

It is generally advisable to automatically detect and react to multiple databases on a server in PHP to streamline the configuration process and ensure consistency. However, manual configuration may be preferred in cases where specific settings or customizations are required for each database. 

// Automatic detection and reaction to multiple databases on a server
$host = 'localhost';
$user = 'username';
$pass = 'password';
$databases = ['database1', 'database2', 'database3'];

foreach ($databases as $database) {
    $conn = new mysqli($host, $user, $pass, $database);
    
    if ($conn->connect_error) {
        die("Connection failed: " . $conn->connect_error);
    } else {
        echo "Connected to database: " . $database . "\n";
        // Perform database operations here
    }
}
