php-language-server/ langserver does not work if not in git directory

Information

VIM version

NVIM v0.3.1 Build type: Release

Operating System: macOS

What went wrong

Opening php files in a non-git directory with php-langserver already installed doesn't trigger php-langserver (as seen shown :ALEInfo).

This is easily remedied by making the current directory a git directory by running git init.

Reproducing the bug

Create a new directory with a blank index.php:

$ mkdir test
$ cd test
$ touch index.php

minimal vimrc:

call plug#begin('~/.vim/plugged')
Plug 'w0rp/ale'
call plug#end()

Installing php-langserver:

$ echo "{
  "minimum-stability": "dev",
  "prefer-stable": true
}" > composer.json
$ composer require felixfbecker/language-server

Open index.php and check :ALEInfo:

$ vim index.php
:ALEInfo<CR>

Then initialize git, open index.php and check :ALEInfo again:

$ git init
$ vim index.php

Notice the extra line indicating that php-language-server.php has been run:

 Command History:

This seems to only be an issue with php-language-server, as eslint started normally with or without being in a git directory.

I don't think this is particularly significant since not being in a git directory is a rare use case, and I'm also not sure if it's an issue with ALE or with php-language-server so I'll just close this issue.
