Simple php script to extract all the MyBB templates used in the default theme, to a folder of your choice. This is mostly for reference, so that grep returns the template name when searching for variables and the like.

extract_mybb_templates.php

<?php
/**
 * A very simple command line php script to extract all the templates from the
 * default MyBB theme into a given folder.
 *
 * This makes it easier to search the templates with grep and similar tools.
 *
 * The .html extension is added to the template names for proper syntax
 * highlighting in most editors.
 *
 * Run the script from the root MyBB installation folder and create the folder
 * beforehand, eg:
 *
 *   $ mkdir templates
 *   $ chmod 777 templates
 *   $ php extract_mybb_templates.php -x
 *
