Before discussing the development process and history of PHP, I think it would be more accurate to ask, “What is PHP?” As is well known, all web page structures are created using HTML. Images, text, etc. are created with HTML and placed in their respective locations, and as a result, when viewed in a browser, we see a web page. Unfortunately, HTML alone is not sufficient to make these web pages interactive. There are many technologies we can use to increase interactivity: CSS, JavaScript, Flash, Silverlight, etc. After enhancing the visuals and interactivity with such technologies, where will we use PHP? How will it be useful? If your only goal is to write a few lines of text for a promotion and you never plan to change the page again for years, then of course PHP won't be useful. However, web pages have become so complex today that using a server-side technology is necessary. For example, let's say you have a news portal and you constantly update it by adding new news content, images, videos, etc. When you visit such a page, you will see that it consists of HTML code. So, can it be done without using a Server Side technology, i.e., coded with HTML? The answer to this question is yes, you can create a news portal without using any server side technology. You can create a page for new news with html and place it inside the index file on your home page.
