SQLiteConnector.php

TLDR

This file SQLiteConnector.php is a part of the Illuminate\Database\Connectors namespace in the Demo Projects project. It contains a class named SQLiteConnector which extends the Connector class and implements the ConnectorInterface interface. The class has a connect method that establishes a connection with a SQLite database based on the given configuration.

Methods

connect

This method is responsible for establishing a database connection. It takes an array $config as a parameter and returns a PDO instance representing the connection.

If the database specified in the configuration is an in-memory database (i.e., :memory:), it creates a connection to an in-memory database.

If the database specified is a file path, it verifies that the database file exists before creating a connection.

If the specified database file doesn't exist, it throws a SQLiteDatabaseDoesNotExistException.

        // SQLite driver will not throw any exception if it does not by default.
