Answer 4

Hi,
unset() function is used to destroy a particular session variable.
eg. unset($_SESSION['success'])

unlink() function is used to remove the file from the file manager. I recently used it in a job portal, where a user when updates his CV, old CV will be replaced with new. So, to remove old one, I used unlink() function.

unset sets defined variable to null and unlink just deletes file
unlink(filename)
unset($variablename)
