VSCode Prettier not formatting PHP

Question

So I've set up vscode with Prettier, but it will not format .php files. .html files are working fine with Prettier. So when I have a .php with HTML code then it will be formatted differently, because I am using Beautify as last option.

How can I make Prettier automatically format .php files and the html code in .php the same as .html files?

Core prettier does not support PHP¹, and thus neither does the plugin for VSCode/VSCodium. Luckily the designers of prettier seems to have thought of this and implemented a plugin system².

According to the prettier-vscode repo, all you need to do to use a plugin is to add it and prettier to your package.json³

So for php support your package.json would need to contain:

{
  "devDependencies": {
    "@prettier/plugin-php": "0.14.3",
    "prettier": "2.0.5"
  }
}
