Hi, if there are some webmaster gurus here, I want to ask about the function of PHP. It seems to me that HTML is a lot easier. I learn about PHP with Linux and getting more and more confuse. Do you think that its useful to learn deeper about PHP today? Why?

HTML is a client side language which literally means it runs on the clients (users) computer, PHP is a sever side language which means it runs on the server which the web site is displayed from. The advantage of PHP is that it can be used to generate html from various sources such as databases, feeds, etc and allows for dynamic content. HTML can only serve static content making it less flexible.

So to answer your question, yes it can be useful to learn PHP but it depends what type of site/content you will be working with. With all the open source CMS (content management systems) such as Joomla, Wordpress, etc .. It may not be necessary to learn PHP (or other server side language) even for larger sited with lots of dynamic content.

Does that clear things up a bit?
