Connection

Connection Modules

The GenericDatabase\Modules\StaticArgs class is responsible for establishing and managing database connections. It uses a strategy pattern to support different database engines. The class provides methods for connecting to a database, executing queries, fetching results, and managing the connection state.

Example Usage

// Implicit and simplified module loading with all environment variables
use GenericDatabase\Modules\StaticArgs;

Code Analysis

Main functionalities

• Establishing and managing database connections
• Supporting different database engines through the strategy pattern
• Executing queries and fetching results
• Managing the connection state (connecting, disconnecting, checking if connected)

Public Methods

• setStrategy(IConnection $strategy): Sets the strategy instance for the database connection.
• getStrategy(): IConnection: Returns the strategy instance for the database connection.
• connect(): Connection: Establishes a database connection using the strategy instance.
• ping(): bool: Pings the database server to check if the connection is still active.
• disconnect(): void: Disconnects from the database.
• isConnected(): bool: Checks if the connection is established.
• quote(mixed ...$params): mixed: Quotes a string for use in an SQL statement.
• prepare(mixed ...$params): mixed: Binds parameters to a prepared query.
• query(mixed ...$params): mixed: Executes an SQL statement and returns the result set.
• exec(mixed ...$params): mixed: Executes an SQL statement and returns the number of affected rows.
• fetch(mixed ...$params): mixed: Fetches the next row from the result set.
• fetchAll(mixed ...$params): mixed: Fetches all rows from the result set.
