Why are some hints missing in phpstorm?

Question

phpstorm

For example, for intval() I type and it tells what arguments the function has and which one follows which. conveniently.
And for include, for example, there is no hint. Yes, this function is simple and obvious, but this is just an example.
There is no for() either, and there are many such functions. for a smart ide, as it is very weak.
How to turn it on?

Answer 1

And for include, for example, there is no hint. There is no for() either, and there are many such functions.

The fact is that these are not functions, but language constructs and their syntax is quite flexible .
If you have problems with them - make yourself a live template (they are already ready, in fact) with the necessary options.
