The HeaderCount extension adds a simple parser function for obtaining the number of headers, or sections, in a page.

The extension is invoked with the {{#headcount:...}} parser function.

Installation

Download and place the file(s) in a directory called HeaderCount in your extensions/ folder.
Add the following code at the bottom of your LocalSettings.php file:
```
wfLoadExtension( 'HeaderCount' );
```
Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

Using this extension is fairly straight forward. The #headcount function has 2 parameters: page, and level.

When the first parameter is omitted ({{#headcount:}}), it will use the current page.

When the second parameter is omitted ({{#headcount:Page}}), it will use 2, as in level 2 headers.
