Show documentation/hover for language constructs

[qiacoucc]

Why there are many PHP core functions without prompt???as :array/isset... https://github.com/JetBrains/phpstorm-stubs/blob/master/standard/_types.php

@qiacoucc array() and isset() are not functions, but language constructs. For example you cannot use them as callback

It's not that big of a deal, everyone needs to learn these rather early. However, hover action would be nice addition anyway.

So will this kind of language structure support hover prompt

I feel like Intelephense seems incomplete without fully supported prompts.

Here are probably all structures, which are not hinted in intelephense (8 in total): https://github.com/JetBrains/phpstorm-stubs/blob/master/standard/_types.php Everything else is hinted properly.
