Cache

Rate limiter backend using cache storage.

class Cache extends \Hazaar\Util\RateLimiter\Backend\Backend

This backend implementation uses a cache adapter to store and manage rate limiting data. It supports configurable cache options and prefixing for rate limiter keys.

Properties

cache

The cache adapter instance used for storing rate limiter data.

private Adapter $cache

prefix

The prefix used for rate limiter cache keys.

private string $prefix = 'rate_limiter_'

index

private array $index

Methods

__construct

Cache rate limiter constructor.

public __construct(array $options): void

Parameters

Parameter	Type	Description
$options	array	the options for the cache

shutdown

Persists all rate limiter data in the local index to the cache.

public shutdown(): void

This method should be called during shutdown to ensure all in-memory rate limiter information is saved to the cache backend.

check

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

public check(string $identifier): void

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

Parameters

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

get

Retrieves and returns the rate limiting information for a given identifier.

public get(string $identifier): void

This method fetches the rate limiting log from the cache using the provided identifier. It removes any log entries that are outside the configured time window. If no log exists, it initializes an empty log array. The resulting information is stored in the local index and returned.

Parameters

Parameter	Type	Description
$identifier	string	the unique identifier for which to retrieve rate limiting data

remove

Removes the rate limit information for the specified identifier.

public remove(string $identifier): void

Parameters

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

getKey

Get the key for rate limiting based on the provided identifier.

private getKey(string $identifier): string

Parameters

Parameter	Type	Description
$identifier	string	the identifier used for rate limiting
