The tutorial says: 3. Use the function unset() to destroy the variable, but the code demonstration uses var_dump();

Are unset() and var_dump() the same function?

The unset() function is used to destroy the specified variable. The var_dump() function used in the code demonstration is used to print the relevant information of the variable.
