Why xdebug marks 587 and 588 as not executed and 589 as executed?

问题

This is the chunk of code with the issue

And this is the legend

回答1:

I've understood what happens. The line 586 has multiple conditions and not all cases are covered and for those cases that are not covered 587 and 588 are listed as not executed.

The legend should be updated though because is confusing.
