On the Internet, all web servers use HTML to receive a request from web browser which is client, and then deliver the necessary data accordingly to the web browser to express it as a general form that human can understand. HTML (Hyper-Text Markup Language) allows a web server to communicate with a web browser and send/receive data each other, and return the processing results back to people.
In this HTML, there are basically static HTML and dynamic HTML. Static HTML means that the content displayed on a web page is always fixed and its content does not change over time. Therefore, if you want to modify the contents, you have to modify the HTML itself to express the page. Dynamic HTML, on the other hand, means HTML with the ability to change the contents of a web page into various forms according to various conditions. It has the function to deliver content in various data and formats by applying the desired conditions without changing the HTML with a basic web page. To construct such dynamic HTML, a separate tool is required. PHP is used for this purpose.
We will not describe all of the PHP functionality here, and we will only introduce functionality to the minimum extent necessary to describe the working principle. Additional learning should be done in a separate way.
