To address the last point, you'd usually call (syntax-ppss) and
examine the returned value. `M-x describe-function parse-partial-sexp`
for its format.

I don't write PHP, so I'm definitely not going to use it, but you may be
interested in this addition to mmm-mode I wrote last weekend:

https://github.com/purcell/mmm-mode/blob/master/mmm-erb.el

Basically, it provides syntax highlighting and smart indentation,
supporting CSS, JS and ERB/EJS subregions. And utility commands already
present in html-mode.

It reuses submodes' indent-line-functions, so extending it to support
PHP, for example, shouldn't be much harder than writing a few regexps
for `mmm-add-group` and `mmm-add-classes` and a scanning function like
`mmm-erb-scan-erb`. That's provided, of course, we'll have some php-mode
package to work with.

mmm-mode is rather heavy, so speed might become an issue with large
files, but it should have room for optimization.
