Is there a way to turn off code highlighting?

I’m finding that in a .php file, one, it’s trying to parse html code outside of <? ?> tags as if it’s php code, and two, that means that if I have an apostrophe somewhere it thinks the entire page is a string (at least until the next one…) It’s annoying, and a mess, and completely useless.

I don’t expect flawless syntax highlighting from a free tool, and I know those types of things can take a while to fix even if they are high on the list, but if I could just turn it off for the pages where it’s not being useful I’d be really happy.

Same with error highlighting, for that matter.

Thanks!
