jmd [1] filed an orphan request for php-language-server [2]: When installed, from what I've tested the majority of files must be available in the same directory in order for php-language-server to "work" (stubs, vendor, src, and bin). When it does work, php-language- server takes a long time to initialize (index all the files) even when installed. This takes at least 5-10 minutes each time you open up a php file.
