## Write your first PHP program

Create a file hello.php in root directory of your web server. If you are using XAMPP , root directory is "C:\xampp\htdocs" and in Ubuntu root directory is /var/www/html/ . Write the following code in hello.php

<?php
echo "Hello world";
?>


For writing code you can you any code editor you like. I recommend using Visual Studio Code , which I use most of the time.

## Running first PHP progran

When you’ve written the code , you need a browser to see the result. Now , open your bowser and go to http://localhost/hello.php . You will see something like this on the browser.

## Explanation

We created a file with .php extension . Files with .php extension are processed and showed in the browser. Generally echo statement shows a string to the output. Here the string is "Hello world".

That’s really simple. Isn’t it ? Feel free to comment if you got any troubles.
