How to properly strip all HTML tags including script and style

If its necessary to clean all HTML tags and JS scripts from any content next PHP function will do the job:

/**
 * Properly strip all HTML tags including script and style
 *
 * This differs from strip_tags() because it removes the contents of
 * the `<script>` and `<style>` tags. E.g. `strip_tags( '<script>something</script>' )`
 * will return 'something'. wp_strip_all_tags will return ''
 *
 * @since 2.9.0
 *
 * @param string $string String containing HTML tags
 * @param bool $remove_breaks optional Whether to remove left over line breaks and white space chars
 * @return string The processed string.
 */
function wp_strip_all_tags($string, $remove_breaks = false) {
	$string = preg_replace( '@<(script|style)[^>]*?>.*?</\\1>@si', '', $string );
	$string = strip_tags($string);

	if ( $remove_breaks )
		$string = preg_replace('/[\r\n\t ]+/', ' ', $string);

	return trim( $string );
}
