<p>I am wondering how I can break up my index.php homepage to multiple php pages (i.e. header.php, footer.php) and build a working index.php page using those separate php pages.  I know WordPress uses this with different functions like:</p>

<pre><code>GetHeader();
GetFoodter();
</code></pre>

<p>But when I tried to use those functions, it errors.  I am guessing they are not native functions to PHP.</p>

<p>What would I need to do to get this functionality?</p>

```
```
include 'header.php';

include 'footer.php';
```
```
