session_start before DOCTYPE

[SJKimpton]

I'm new to Phoenix code and struggling a bit to adjust.
My first problem when adapting old code is that
In PHP session_start() must procede any code (including DOCTYPE html sent to the client. When I do this, I get
failed to tokenize "<!DOCTYPE ..." and this stops further checking of my code.
If this is a bug, I don't know how to report it. If it's not a bug, what can I do?

@SJKimpton, the error message you’re seeing is because the PHP language server has not been integrated into Phoenix Code yet. It’s on our to-do list, but we likely won’t be able to implement it this year. In the meantime, if you’d like to hide the error message, you can add the following line to your preferences file: "HTMLLint.disabled": true,. Read this docs if you need any help in editing the preferences.
