Cache Function for PHP

This is a fantastic function that will allow you to cache your data. By default it will cache using memcache, however if you do not have memcache installed or a connection cannot be achieved it will fall back to file based cache.

The single function supports cache read, cache write, cache clear key and cache clear all. The cached data can be given an expirey time so that your data does not become stale.

Usage is very simple and the performance results of caching using memcache are fantastic.

Prevent Cron Task Overlap in CakePHP

If you have a task that runs every 5 minutes, and it takes more than 5 minutes to run then the next task will start causing even more server load. This effect may stack up and eventually cause your server to come to a grinding halt. For this reason it is very important that your scheduled tasks do not overlap.

I have a domain where I keep all my pictures and I would like to be able to use multiple domains to access those images.

Clear All Cache in Drupal

Quick code snippet, just drop this into clearcache.php and then load it in your browser.

MySQL Ordering the Group By

A problem that I have faced with SQL many times is pre-ordering the GROUP BY clause.

When you GROUP BY, MySQL will return a set of records which I call representing records. These records represent the group that is selected.

For example select id from test group by class will return one representing record per unique value of the class field. The problem with this is that you have no control over which record will represent the group.
