phpls

phpls is a fast and smart language server for PHP written in Go.

Features

• Very fast indexing: Responsive right away, fully indexed in a matter of seconds
• Smart go to definition: WIP
  • Understands type hints
  • Understands PHPDoc tags (generics to-do)
  • Go to definition inside PHPDoc, (like on the @param type or @inheritdoc)
• Context-aware smart completion: WIP
  • Suggests everything available from the current scope
  • Automatically adds use statements
  • Can complete nesting $this->config->get()->version
• Proxy your favorite tools, create an issue if yours is missing:
  • Efficiently ran by keeping processes running
  • Configurable on-change or on-save
  • Configurable binaries, php version, standards
  • PHPCS
  • PHPStan
• Basic hover, on the to-do list to greatly improve

Installation

More installation methods will be added soon.

Building yourself

Make sure you have git and go installed.

git clone --recurse-submodules https://github.com/laytan/phpls.git
go build -o phpls cmd/phpls/main.go

Symlink the executable to a folder that's in your path, example:

sudo ln phpls /usr/local/bin/phpls

Or if you're on windows, add it to your path.

Editor setup

Neovim LSP Config

These configs have to be manually added for now, will merge into the LSP config repo soon.

require('lspconfig.configs').phpls = {
  default_config = {
	cmd = { 'phpls' },
	filetypes = { 'php' },
	root_dir = function(pattern)
	  local cwd = vim.loop.cwd()
	  local root = util.root_pattern('.git')(pattern)

	  return util.path.is_descendant(cwd, root) and cwd or root
	end,
  },
}

require('lspconfig').phpls.setup({})

VSCode extension

Coming soon.

Running a language server is done using your IDE/editor most of the time, but here are the options available:

Configuration

The following file names are seen as phpls configuration files: phpls.json, .phpls.json, phpls.yml, .phpls.yml, phpls.yaml, and .phpls.yaml

These files are recognized when they are in any of the following directories:

• Linux and Mac OS: ~/.config/, ~/, $(pwd)/
• Windows: %AppData%/, $(pwd)/

These files are checked top to bottom, with later files overwriting the former.

Configuration files are then overwritten by environment variables, with the prefix 'phpls_', so setting the php version can for example be done with 'phpls_PHP_VERSION=8'.

You can also provide command line flags instead of a config file or environment variables.

See this file for the configuration schema. If possible, soon, we will submit this schema to the schema repository so editors will use it for completion and documentation.
