Vim: How to indent html code correctly in php file?

In php file :

<?php
...
?>
<html>

</html>

I could not indent the html source code with operator =.

How could I indent it?


Solution 1:

My workaround for this is to temporarily switch to html mode, mark region and indent, and then go back to php mode.

:set filetype=html
" mark html code
=
:set filetype=php

Solution 2:

There is an entry on the Vim Tips Wiki that details how to enable indenting of both PHP and HTML areas of PHP files: http://vim.wikia.com/wiki/Better_indent_support_for_php_with_html
