html inside php files

[lcvworkflow]

I noticed that the server does not work when I edit a php file that also contains html code. Can it be configured to detect the html code? If I set the command :set filetype=html it will work, but the intelephense server, which I use in php programming, stops. I need coc-html to figure out where the html code is placed in file and treat it as such. Is this possible?
