LibSQL has 4 types of connections to interact with the database: In-Memory Connection, Local Connection, Remote Connection, and Remote Replica Connection (Embedded Replica).

​
In-Memory Connection

$params = [
    "url"               => ":memory:",
    'driverClass'       => \Darkterminal\LibSQL\DBAL\Driver::class,
];

​
Local Connection

$params = [
    "url"               => "database.db",
    'driverClass'       => \Darkterminal\LibSQL\DBAL\Driver::class,
];
If you want to create Remote Connection or Remote Replica (Embedded Replica) Connection, you will need an existing database to continue. If you don’t have one, create one. Get the database URL: 
turso db show --url <database-name>
Get the database authentication token: 
turso db tokens create <database-name>
If you use .env file, assign credentials to the environment variables inside .env. 
TURSO_DATABASE_URL=
TURSO_AUTH_TOKEN=

​
Remote Connection

$params = [
    "auth_token"        => "<your-database-auth-token-from-turso>",
    "sync_url"          => "<your-database-url-from-turso>",
    'driverClass'       => \Darkterminal\LibSQL\DBAL\Driver::class,
];

​
Remote Replica (Embedded Replica) Connection

$params = [
    "url"               => "database.db",
    "auth_token"        => "<your-database-auth-token-from-turso>",
    "sync_url"          => "<your-database-url-from-turso>",
    "sync_interval"     => 5,    // Optional, default is: 5 in seconds
    "read_your_writes"  => true, // Optional, default is: true
    "encryption_key"    => "",   // Optional, default is: empty
    'driverClass'       => \Darkterminal\LibSQL\DBAL\Driver::class,
];
