For a web site to be competitive today, it must be interactive, dynamic, and capable of performing on-line transactions. Gone are the days, when entire web sites were created using static pages. Today, web developers are using tools and programming languages to help them create customized web pages, develop shopping cart applications, and track user's behaviors. To meet these development challenges, this paper will examine the strengths and weakness of one of the latest programming languages used to create dynamic web pages known as 'PHP Hypertext Preprocessor' (PHP). This software, originally known as Personal Home Pages, was developed in 1997 and is currently being used in over 10 million domains.
