PHP : Everything to know....
Every individual, getting started with web development learns programming languages like HTML, CSS and JS. These are the three fundamental parts of any beginner's course for programming web scripts. However, when it comes to actual development, making those scripts viable, functional and running them in real-time. There arises a need for something that can interpret the code, handle the data, perform inter-activities, something that could bridge the gap between the data from the main server to the websites you visit, photos you post, videos you like and even the blog you are reading at this very moment. We need PHP!

To give a basic explanation PHP- stands for Hypertext Preprocessor, is a server-side, scripting language, used for web development. To further understand the meaning of this, let's start with the browser and understand how a code, actually is interpreted.

A browser is nothing but an interpreter that interprets or understands the code and converts it into visual display. Easy? Now, there are two types of codes that are processed either at the client-side or at the server-side.

'Client-side' are the actions that takes place on the user's (the client's) computer.

'Server-side' are that the actions that takes place on a web server where the HTML, CSS and JS programs run.

PHP is a software installed on a computer, to process at the Server-side along with Apache and MySQL. They are all essentially peace of software's designs to serve web-pages to the client's browser.

When we go to any (.com) website that request gets translated into IP address by what is called a DNS (Domain Name Server). Then the browser gets the IP address and makes a connection with that particular server of that website or webpage.

Firstly, the request is received by Apache, if the requested webpage includes the (.php) extension, the request is sent to PHP process engine which finds and render the request and then the request is made to MySQL. The data is collected from MySQL database, then the PHP codes convert them into result in whatever languages it may include. It maybe HTML, CSS or JS before sending it back to Apache interpreter. The Apache then forwards the interpretation to the browser where it is displayed as the way it is programmed to be.

PHP is called preprocessor i.e. something it is processed on server side before sending it back to MySQL.

What it means by a Scripting Language is that we can write PHP code inputs for other codes to make the inter-activities of applications of the web page. It allows you to add conditional logic, requests databases, process HTTP request and a whole lot more you can do with just HTML, CSS and JS.

PHP allows elements to interact. It helps create dynamic web pages, and robust applications to do something extraordinary then just display information.
