Some advance useful function

<?php

/**
 * Returns the number of words in a string.
 * As far as I have tested, it is very accurate.
 * The string can have HTML in it,
 * but you should do something like this first:
 *
 *    $search = array(
 *      '@<script[^>]*?>.*?</script>@si',
 *      '@<style[^>]*?>.*?</style>@siU',
 *      '@<![sS]*?--[ tnr]*>@'
 *    );
 *    $html = preg_replace($search, '', $html);
