What is PHP?
PHP means PHP Hyper-text Preprocessor.
PHP ==> is a scripting language for creating a dynamic web page.
Dynamic web page means that the user does not only views the web page but there is an interactivity between the user and the web page.
How to create this kind of interactivity? Well, it’s only by client-side or server-side.
a. client-side = The scripting language or code of the page/program is processed only by the browser. This means that when you view the web page and open the source code, is that whatever you have encoded is the same as it shows.
b. server-side = the server is the one processing the code which will make the PHP code invisible as the user try to view the source code of your web page. Why is this? Because the one processing the code is server, as it process it translates the code into HTML. This HTML code will be the visible code for the user as it try to view the source code.
PHP ==> open-source, server-side, HTML embedded scripting language.
Open Source - it means that you can open the source code on how a program is created.
