Cache - PHP File-Based Cache

This is a simple PHP file-based caching system with support for cache monitoring and encryption. It allows you to securely cache data and monitor cache usage in your PHP applications.

Features

File-based caching: Data is stored in files on the filesystem.
Cache monitoring: Track cache hits, misses, and cache size.
Encryption support: Encrypt cached data for security.
Customizable expiry: Set expiry time for cached data.

Installation

Clone the repository or download the Cache.php file.
Include the Cache.php file in your PHP project.

Usage

1. Initialization

// Include the Cache class
require_once "Cache.php";

// Create a new Cache instance with cache directory and encryption key
$cache = new Cache("./cache", "my_secret_key");

2. Caching Data

// Cache data with optional expiry time (default: no expiry)
$cache->set("key", "value", 3600); // Cache "value" with key "key" for 1 hour

3. Retrieving Data

// Retrieve cached data
if ($cachedData = $cache->get("key");) {
    echo "Cached data: " . $cachedData; // return "value" - if set
} else {
    echo "Data not found in cache.";
    // You now may execute a call to the Database and then set the cache
}

4. Clearing Cache

// Clear cache for a specific key
$cache->clearCache("key");

// Clear entire cache
$cache->clearCache();

5. Retrieving Cache Hits and Misses

// Get cache hits and misses
echo "Cache Hits: " . $cache->getCacheHits() . PHP_EOL;
echo "Cache Misses: " . $cache->getCacheMisses() . PHP_EOL;

6. Retrieving Cache Size

// Get cache size
echo "Cache Size: " . $cache->getCacheSize() . " bytes" . PHP_EOL;
