title: Sublime 3 editor syntax highlighting PHP + HTML not working
body: <p>Basically my issue is when I set the text mode to PHP my HTML is losing it's syntax highlighting whilst using the Material colour theme. It highlights all HTML as white and if i switch to HTML it highlight all PHP as white. This issue started yesterday after upgrading to Sublime build 3103. Anyone know how to fix it?</p>
