We need to find the solution to the question

Reverse the elements $3-2-1-$NULL. PHP PHP does not come with a built-in null() method. It is called is null (). and the distinction between is null() and empty() is empty — Check to see if a variable is empty. If the variable is an empty string, false, array(), NULL, "$0$?, $0$, or an unset variable, it will return true. is null — Determines if a variable is NULL. Only when the variable is null does it return true. The distinction between isset() and is null() is that the former only applies to declared variables, whereas the latter does the opposite.

The correct answer is Reverse the elements $3-2-1-$NULL.
