Overview

The ObCache class is a versatile and easy-to-use PHP class designed for caching in WordPress environments. It provides functionality to manage caching operations with ease, supporting operations such as setting, getting, and removing cached data. This class is particularly useful in scenarios where data retrieval from a cache is preferred over repeatedly querying a database or performing complex computations.

Features

• Flexible Caching Control: Control whether caching is enabled or disabled.
• Easy Initialization: Instantiation via a constructor or a static init method.
• Data Storage and Retrieval: Methods for setting and retrieving cached data.
• Cache Removal: Functionality to remove specific cache entries.

Usage

Instantiation

Directly via constructor:

$cache = new ObCache();

Using the static init method:

$cache = ObCache::init();

Setting Cache Mode

Enable or disable caching:

$cache->set_cache_allowed(true); // Enable caching
$cache->set_cache_allowed(false); // Disable caching

Setting Data in Cache

Use the set method to cache data:

$cache->set('cache_key', function() {
    // Data generation logic
    return $data;
}, 3600); // 3600 seconds expiration

Retrieving Data from Cache

Use the get method to retrieve or generate and cache data:

$data = $cache->get('cache_key', function() {
    // Data generation logic
    return $data;
}, 3600);

Removing Data from Cache

Use the forget method to remove data from the cache:

$cache->forget('cache_key');

Integration with WordPress

This class utilizes WordPress caching functions (wp_cache_set, wp_cache_get, wp_cache_delete) and is designed to work within a WordPress environment.

Notes

• The class uses a protected constant OBC_CACHE_GROUP to define a cache group called evp_cached for better organization and management of cached items.
• Cache mode status can be checked using is_cache_allowed() method.
• When caching is disabled, the set and get methods directly handle data without caching.
