Note Submitter: kamil dot derkacz at o2 dot pl ---- I can't understand how unset() function can't remove the variables (assign them null instead). If we create a new var e.g $low and want to echo it we'll get null. When we assign a 5 value to the $low var and next unset this variable, we'll get null too as above.
