...personalities, maid cafes and may others. SMAP is a Jpop boy band with immense popularity from Japan and is one form of Japanese popular culture. Darling-Wolf suggests that SMAP's popularity is due to its careful construction of appeal and masculinity. SMAP is not well-known for their talents in singing, but rather for depicting Japanese personalities. Darling-Wolf refers to SMAP members as 'life-sized' pop idols (Aoyagi) who personifies a typical Japanese boy or girl which allows audiences to relate to them well. This is supported by Yano's research which highlights that fans form emotional bonds and connections with celebrities due to their charisma and personalities. Darling-Wolf that SMAP is popular is due to its intertextuality from appearing in TV shows, movies, talk shows and many more media forms which allows fans to feel a proximity or closeness. Intertextuality allows SMAP to be able to portray their personalities better and reach out to more audiences, which enables them to connect with their audience. Darling-Wolf argues that SMAP's fame is highly due to its constructed appeal of masculinity, which creates the 'perfect female fantasy'. SMAP members portray pluralities of masculinities which involve masculinity as a sensitive man and also a violent one. It is important to note that SMAP is always portrayed as the victim in a movie and though they may use violence, Darling-Wolf identifies that their violence is mitigated by their sensitive side of masculinity.

...scripting on the internet was something which very few people even attempted, let alone mastered. Recently though, more and more people have been building their own websites and scripting languages have become more important. Because of this, scripting languages are becomming easier to learn and PHP is one of the easiest and most powerful yet. What Is PHP? PHP stands for Hypertext Preprocessor and is a server-side language. This means that the script is run on your web server, not on the user's browser, so you do not need to worry about compatibility issues. PHP is relatively new (compared to languages such as Perl (CGI) and Java) but is quickly becomming one of the most popular scripting languages on the internet. Why PHP? You may be wondering why you should choose PHP over other languages such as Perl or even why you should learn a scripting language at all. I will deal with learning scripting languages first. Learning a scripting language, or even understanding one, can open up huge new possibilities for your website. Although you can download pre-made scripts from sites like Hotscripts, these will often contain advertising for the author or will not do exactly what you want. With an understanding of a scripting language you can easily edit these scripts to do what you want, or even create your own scripts. Using scripts on your website allows you to add many new 'interactive' features like feedback forms, guestbooks, message boards, counters and even more advanced features...

Trademarks Page 1 of 20 developerWorks® ibm.com/developerWorks The need for dynamic content The Web is no longer static; it's dynamic. As the information content of the Web grows, so does the need to make Web sites more dynamic. Think of an e-shop that has 1,000 products. The owner has to create 1,000 Web pages (one for each product), and whenever anything changes, the owner has to change all those pages. Ouch! Wouldn't it be easier to have only one page that created and served the content on the fly from the information about the products stored in a database, depending on the client request? Nowadays sites have to change constantly and provide up-to-date news, information, stock prices, and customized pages. PHP and SQL are two ways to make your site dynamic.
