title: How to set php executable path php.validate.executablePath in vscode when php is set inside docker container?
body: <p>I have a development environment based in docker.</p>
  
  <p>Everytime that I open VSCode I get this message:</p>
  
  <blockquote>
    <p>Cannot validate since no PHP executable is set. Use the setting
    'php.validate.executablePath' to configure the PHP executable.</p>
  </blockquote>
  
  <p>Somebody know how to set php.validate.executablePath in this case?</p>
  
  <p>I have no idea how to do it.</p>
