# Hello world example

To create a simple test script, create a new file called `helloworld.php` in your root folder with the following PHP code: 

```php
<?php

require_once("class2.php"); // Load e107's main classes and functionalities
require_once(HEADERF); // Load and output the theme's HTML for the $HEADER.

// Option 1:
echo "Hello World";

// Option 2:
$ns = e107::getRender(); // Load rendering object. 
$ns->tablerender("My Caption", "Hello World");  // Render Caption and Text according to Theme style. 

require_once(FOOTERF); // Load and output the theme's HTML for the $FOOTER. 
exit; 
```

Then point your browser to `www.yoursite.com/helloworld.php`and you're ready!
