# Why "Hello World"?

The first program that most aspiring programmers write is the classic **“Hello World”** program. The purpose of this program is to display the text **“Hello World!”** to the user.

The **“Hello World”** example is somewhat famous as it is often the first program presented when introducing a programming language.

The most widely used language construct to print output in PHP is `echo`.

Alternatively, you can also use `print`: 



PHP also provides C-style `printf` and related functions. Run the following code: 

<?php
printf("%s\n", "Hello, World!");
?>
