Add php-language-server

[mjlbach]

Request from reddit, I can't test because I can't get composer to install php language server.

[sunzoje]

Shouldn't this be php_language_server?

[mjlbach]

No, we use the official name in the docs. Substitute underscores is just a lua thing.

[sunzoje]

Sorry, I'm not clear. It requires sumneko_lua for php server?

[mjlbach]

Nope, it's a typo

[mjlbach]

@sunzoje did you try this? Does it work?

[sunzoje]

I don't use php that much. Let me test and report back to you.

:lua print(vim.inspect(vim.lsp.buf_get_clients())) returns {}.

Did you generate stubs like in the installation instructions?

failed to open stream: No such file or directory in /private/tmp/phptest/vendor/felixfbecker/language-server/src/Index/StubsIndex.php

[sunzoje]

I missed that part. I thought that part is optional.

[sunzoje]

I'm not able to generate stubs; getting following error:

Parsing file:///private/tmp/phptest/vendor/jetbrains/phpstorm-stubs/standard/standard_8.php
Script LanguageServer\ComposerScripts::parseStubs handling the parse-stubs event terminated with an exception
  [RuntimeException]
  A type is missing before a type separator

This issue is documented in felixfbecker/php-language-server#795.
Once rectifying the issue, the addition of this server is working.

[Mte90]

It seems that to use that php LSP it is required a local patched version or that someone does a fork.

Very sad as it is seems that is abandoned. At the same time is the most used and famous language server for php -.-'
