Introducing ElseIf to your PHP
I’ve always been very indecisive when it comes to just about everything, so the option for an ‘elseif” in PHP runs right up my alley. Following our previous discussion on PHP IF Statements, the elseif introduces more options for your script to run with.

The Blogosaurus on CNN?
Haha, awesome. Check out the link love make-out on CNN, regarding my article about the cost of C02 emissions. The best part is my slam towards Windows machines is just enough in there for the trained eye.

Following my previous post about SQL Injection attacks, and what bad PHP code can do to your project and/or client, I wanted to pass along some important info on how to protect your code.

SQL Injection Attacks
While working on a simple php script, I learned I was opening myself up for “ripe SQL Injection” per a developer’s exact words. SQL Injection is an interesting and valuable issue on PHP to discuss and research. While reviewing the Wiki article about SQL Injection, I was intrigued by some attacks,
