PHP

For those that may find it useful here are some various bit of PHP I have written that you may use.

MySql Wrapper Class: A class that I used for handling all MySql connections on codefisher.org and a few other sites. It was written to simplify 1) connecting to multiple databases 2) error handling 3) only connecting when needed, that is if the page never runs a SQL query, a connection to the database is never established.
Google Safe Browsing: Google offer an API for checking if a link is from a phishing or malware site. Wanting to leverage this functionality on Xrl.in I wrote the needed functions/classes that hide all the hard parts and make it simple to incorporate into your site.
Lite Atom Feed Creator: What to start writing your own atom feed? Want a very simple script to use? Well this might just fill the bill. Control panel and feed all in one file, and very easy to set up just edit the settings at the very start of the file.
