difference between empty() and null?

what is the difference between the two? how can if(!empty($field)) return true, but the same variable, pass as false when asked if it's null?

Hi there

you may need to see these links:

http://php.net/manual/en/language.types.null.php

http://php.net/manual/en/function.empty.php

think of 'null' as 'unassigned', and 'empty' as 'assigned but no value'. this sentences are not true at all but maybe help to remember difference.
