 It's an Open Source web server with all the tools and language support built-in to it. It's ready to use and makes it easier for developers to take their code and host it locally and test the same. XAMPP is a local web server which helps you to make the web application at your system and run at the browser at local environment at your local machine.

In your local machine you would need to use specially Apache server and MySQL That will be enough to make a web application and test it on your local server, and later you can shift this code to the live server. XAMPP stands for Cross-Platform (X), Apache (A), MariaDB (M), PHP (P) and Perl (P). It is a simple, lightweight Apache distribution that makes it extremely easy for developers to create a local web server for testing purposes. Everything needed to set up a web server – server application (Apache), database (MariaDB), and scripting language (PHP) – is included in an extractable file. XAMPP is also cross-platform, which means it works equally well on Linux, Mac and Windows.

The XAMPP lite package contains an application called Localhost/Server/Xampp which allows developers to administer and maintain MySQL databases. For the remainder of this article we will be using phpMyAdmin to create a database and table, and enter test data used in address book program. In order to start phpMyAdmin, you must first copy the phpMyAdmin folder from the xampplite directory and place it into the xampplite\htdocs directory. Before testing phpMyAdmin, make sure that both Apache and MySQL are running by opening their respective batch files: apache _start.bat and mysql_start.bat. Along with Apache and MySQL running in the background, type http://localhost/ phpMyAdmin/ into your internet browser. If successful, you will be presented with a phpMyAdmin start page similar to the one in figure

It is a free and open source cross-platform web server solution stack package developed by Apache HTTP Server, MariaDB database, and interpreters for scripts written in the PHP and Perl programming languages. XAMPP stands for Cross-Platform(X), Apache(A), MariaDB(M), PHP(P) and Perl(P). Everything needed to set up a web server-server application(apache), database(MariaDB), and scripting language(PHP)- is included in an extractable file. XAMPP is also cross-platform, which means it works equally well on Linux, Mac and Windows. Since most actual web server deployments use the same components as XAMPP, it makes transitioning from a local test server to a live server extremely easy as well. USB Webserver is a combination of the popular webserver software: Apache MySQL, Php and phpMyAdmin. With USBWebserver it is possible to develop and show your Php websites, everywhere and anytime.
