How to use XDebug?

Question

xdebug

I use XDebug, the problem is that when tracing it does not go to a lower level, but simply works out line by line in the file where the breakpoint was. How to make him look deeper?
breakpoint
function call X
further actions.
Passes the function call without looking inside.

Answer 1

In PhpStorm:
f7 - go inside the function
f8 - go to the next line
