This function displays information about the values of variables
|
||||
in a way that's readable by humans. If given a string, integer
|
||||
or double, the value itself will be printed. If given an array,
|
||||
values will be presented in a format that shows keys and
|
||||
elements. Similar notation is used for objects.
