1.What is the difference between a static and Dynamic Web site?
2.What is the meaning of Open Source Software?
3.Why was PHP developed, what it is used for, and where can you get it?
4.What are the benefits of using PHP and MySQL?

The above FOUR questions you should know before go to this topic.

A static website is one that is written in HTML only. Each page is a separate document and there is no database that it draws on. What this means functionally is that the only way to edit the site is to go into each page and edit the HTML - So you would have to do it yourself using a web page editor such as FrontPage or Dreamweaver, or pay your web developer to make updates for you.

A dynamic website is created by webdevelopers who are strong in ASP.Net, PHP, JAVA and more... This website pages contains data is retrieved from certain database. Each time the viewer entering a page, the contents of that page is retrieved from the database. The administrator can change the content and images from admin panel. This is one that changes or customizes itself frequently and automatically.

Open-Source Software (OSS) is computer software that is available in source code form: the source code and certain other rights normally reserved for copyright holders are provided under a software license that permits users to study, change, improve and at times also to distribute the software.Open Source Software means it is a free software and no need to buy, we can use full functionallities from this software with certain Terms & Conditions. This license allows modifications and derived works, and allows us to be distributed under the same terms as the license of the original software.

PHP developed for less script, time saving, Free Open Source Software and runs on different platforms such as Windows, Linux, Unix, etc. PHP compatible with almost all servers used today such as Apache, IIS, etc.

The PHP scripting language resembles JavaScript, Java, and Perl, These languages all share a common ancestor, the C programming language. PHP has full access to the information that the server has, and very little access to information that the client has. In fact, it only has information that the client tells the server and that the server passes on to PHP. Because it is on the server, however, PHP cannot be modified by the client. While you cannot necessarily trust the information that the client gives to PHP, you can trust that your PHP is doing what you told it to do. Because PHP is on the server end, your PHP scripts can affect your server -- such as by keeping an activity log or updating a database.

One of the main reasons that businesses choose PHP is its simplicity and ease of use. PHP competes against a number of other web scripting solutions such as Active Server Pages and PERL, but none of these languages are as easy to learn as PHP. Further, some languages require a moderate amount of programming background before a developer can get up to speed in development. With PHP, however, even non-programmers have been able to develop web-based solutions within a matter of days after going through the basic tutorials on PHP. PHP commands are simply embedded into the same web page with HTML commands, and execute on the server to deliver the web pages to the user.

Another big advantage of PHP is its interoperability with multiple operating systems. A company can use PHP with either Linux, Windows or Macs for example. They can also use PHP with the popular open source Apache server. Compare that with Microsoft’s Active Server Pages, by contrast, which is primarily designed for Microsoft-enabled servers. Portability is becoming a chief concern for businesses that use one or more operating systems in their businesses. Businesses save money by using PHP to leverage their existing I.S. resources rather than investing large sums of money to purchase proprietary products.
