Requires at least: 3.0
Tested up to: 3.2.1
Stable tag: trunk

Database result serialization.

== Description ==
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.

== Installation ==
1. Place entire /wpdb-cache-money/ directory to the /wp-content/plugins/ directory
1. Activate the plugin through the 'Plugins' menu in WordPress
1. Bling

== Frequently Asked Questions ==
= 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.
