PHP roots and languageserver improvements

[grasegger]

Hello,

this pull request adds two things to the default languages.toml:

Setting the default lsp to intelephense

After a lot of testing of different lsp implementations for php I found intelephense to be the best one for my projects (laravel, TYPO3, Wordpress). The free version offers a lot of value and the professional version is very affordable (15€). I understand that it can be controversial depending on a paid product for full functionality as an open source project, but as a developer I also value tools that save my time.

Defining roots

I added composer.json (composer is the de facto standard package manager for PHP) and index.php (still the default entry point for all modern projects) as workspace roots.

IMO this is not a big deal since it is easy for someone to override this setting in their own languages.toml if they want to use any other language server, e.g.:

# on unix: ~/.config/helix/languages.toml
[[language]]
name = "php"
language-server = { command = "some-foss-php-ls" }

I think

is very reasonable :)

When I tried all the different PHP language servers I also found that the free intelephense was by far the best!

I added intelephense https://github.com/helix-editor/helix/wiki/How-to-install-the-default-language-servers#intelephense to the WIKI

Thanks, I was not aware of that page, it probably should be part of the docs? 🤔

Ah yep, we should probably link to that from the readme and maybe the docs here
