April 19th, 2009 71 comments

MVC Architecture has implemented by Trygve Reenskaug at 1979 for the first time. It was implemented on Smalltalk at Xerox labs. Then benefits and advantages of this architecture has been accepted by most of the coders and software engineers.

It was an information about MVC’s history above. Now lets talk about what really MVC is. What do you understand from MVC. The word M stands for Model, V stands for View and C stands for Controller. I am going to mention about each item.

The figure above may help you while thinking what structure it might have. Let’s start with Model.

It handles data processing and database works part. Model processes events sent by controller. After processing these events then it sends processed data to controller (thus, controller may reprocess it) or directly to view side.

View:
View prepares an interface to show to the user. Controller or model tells view what to show to the user. Also view handles requests from user and informs controller.

What is PHP?

April 18th, 2009 No comments

First of all i need to say that PHP is a language which you are going to in love with. (That is of course if you are a developer ) PHP stands for PHP: Hypertext Processsor.

To start with it you should have knowledge about basic scripting and HTML language.

PHP is totaly free to use and download that is because it is an open source. Well there are many scripting languages on the earth. PHP is server-side scripting language. It means codes are executing on the server-side not in the client-side.

Thus, clients cannot see your php script, a client can only see pure html content. Now i can say PHP is secure langauge since user cannot see your PHP code. How it works? For instance, a client (user) requests a webpage from your server. Then your server executes php code and returns pure html content to the user. And user have no chance to see what is going on at the server-side.

Extensions : .php, .php3, .phtml
