File

Rate limiter backend using file-based storage.

class File extends \Hazaar\Util\RateLimiter\Backend\Backend

This backend implementation uses a BTree database to store and manage rate limiting data. It supports configurable file paths and compaction intervals for efficient storage management.

Properties

db

The BTree database instance used for storing rate limiter data.

private BTree $db

index

private array $index

created

public int $created

compactInterval

The interval (in seconds) after which the database should be compacted.

private int $compactInterval = 3600

Methods

__construct

File rate limiter constructor.

public __construct(array $options): void

Parameters

Parameter	Type	Description
$options	array	the options for the file

shutdown

Performs shutdown operations for the rate limiter backend.

public shutdown(): void

This method saves any updated rate limit information to the database and, if the compact interval has elapsed since creation, compacts the database to optimize storage.

check

Checks and updates the rate limit information for a given identifier.

public check(string $identifier): void

Retrieves the current rate limit data for the specified identifier, appends the current timestamp to the log, updates the internal index, and returns the updated information.

Parameters

Parameter	Type	Description
$identifier	string	the unique identifier to check and update rate limit information for

get

Retrieves and updates the rate limit information for a given identifier.

public get(string $identifier): void

This method fetches the rate limit log for the specified identifier from the database. It removes any log entries that are outside the configured time window (windowLength). If no log exists for the identifier, it initializes an empty log.

Parameters

Parameter	Type	Description
$identifier	string	the unique identifier for which to retrieve rate limit information

remove

Removes the rate limiter entry associated with the given identifier.

public remove(string $identifier): void

Parameters

Parameter	Type	Description
$identifier	string	the unique identifier for the rate limiter entry to remove
