描述
Cache Money stores all database result sets on the filesystem as serialized data, by using the oft-neglectged wp-content/db.php to extend the normal $wpdb class. Result sets will be updated as needed on a user by user basis when they do actions that perform update queries.
Please note that this is not a full scale page cache, like WP-Cache or WP Super Cache, although this will work just fine in conjunction. Cache Money is meant for sites with constantly changing content, where a full cache may not be suitable.
Tested with WordPress and WordPress MU 2.8.0 ~ 3.1
Requires PHP 5, like all good PHP apps.

常见问题
This doesn’t do anything!
Yes it does. Hey, didn’t you ask this question over on my other plugin too?
I need the cache to be cleared at a different interval than 5 minutes.
Change $cacheMoney->threshold to whatever number of seconds you wish.
How can I tell if this is working?
The directory wp-content/plugins/wpdb-cache-money/ should be full of files with names similar to 4a13fc6a615ac14cc3f58160ce9c52f3.php. If not, check to make sure this directory is writable by your server. echo $wpdb->stats(TRUE) will give you a result like q: 9 | c: 6 | m: 9.055 t: 0.171. q is the number of actual database queries, c is the number of cached queries, m is the memory usage in megabytes, and t is the time in seconds to render the page. echo $wpdb->stats() will do the same, wrapped in an html comment, for times when you need to be discrete. There is also a profiler method – echo $wpdb->profiler(). You will need to make sure $cacheMoney->useProfiler is set to TRUE to use this. The default for the profiler is to sort the queries by length of time descending. $wpdb->profiler(FALSE) will show the queries in the order performed.
