XAMPP stands for Cross-Platform (X), Apache (A), MySQL (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 you need to set up a web server – server application (Apache), database (MySQL), and scripting language (PHP) – is included in a simple 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.
Web development using XAMPP is especially beginner friendly, as this popular PHP and MySQL for beginners course will teach you.
