How to set php executable path php.validate.executablePath in vscode when php is set inside docker container?

Question

I have a development environment based in docker.

Everytime that I open VSCode I get this message:

Cannot validate since no PHP executable is set.

Answer 1

I simply used double forward slashes and it worked, like so: "php.validate.executablePath": "C:\xampp\php\php.exe",
