@checkRateLimit - Rate Limiting Requests

The @checkRateLimit directive in Ahmed PHP Template Engine allows you to limit the number of requests a user can make within a specific time frame to prevent abuse.

Syntax

@checkRateLimit(key, maxRequests, timeWindow)

  • key: A unique identifier for the request source (e.g., IP address, user ID).

  • maxRequests: The maximum number of allowed requests within the given time window.

  • timeWindow: The time frame in seconds for rate limiting.

Description

  • This directive checks if the given key has exceeded the allowed request limit.

  • If the limit is exceeded, further requests are blocked until the time window resets.

  • Helps prevent spam, brute-force attacks, and excessive API usage.

Example

@checkRateLimit('user_123', 10, 60)

Expected Behavior

  • If user_123 makes more than 10 requests within 60 seconds, further requests will be denied.

  • The limit resets after the time window expires.

  • Can be applied globally or to specific sections of the template.

Notes

  • Ensure the directive is used in performance-sensitive areas.

  • Works best when combined with logging and error handling.

  • Can be configured dynamically for different user roles.
