This summer I have enrolled in a Dynamic Websites independent study for my graduate program. The course will focus mainly on developing PHP programming skills, something I have been lacking and interested in developing for some time.
This week I have been reading the first five chapters of Beginning PHP 5.3, Doyle (2010). Chapter 1 gave a good overview of PHP and it’s advantages. It drew comparisons to other programming languages, which I found interesting coming from a ColdFusion background.

This week I have been reviewing the first 5 chapters of Beginning PHP 5.3, which has been giving me a good solid introduction to PHP.
