The Docket cache is a persistent WordPress Object Cache that is stored as a plain PHP code. Intends to provide an alternative option for those who can't use Redis or Memcached server.
Rather than using serialize and unserialize a PHP object to store into flat files, this plugin stores data by converting the object into plain PHP code which results in faster data retrieval and better performance with Zend OPcache enabled.
When it comes to reliable persistent Object Cache in WordPress, Redis or Memcached comes on top. However, those solutions require knowledge of server and rarely available at low cost or shared hosting servers
The only solution is to store the object caches into files. With WordPress, exporting the PHP objects are not easy, most plugin that implements file-based solution will serialize and unserialize the object to store and retrieve the data.
Docket Cache takes a better approach by turning the object cache into plain PHP code. This solution is faster since WordPress can use the cache directly without running other operations.
