note 48203 deleted from language.references.unset by sean

Note Submitter: mangelp at ieee dot org ---- Bishop: Sorry but you are making a mistake. When you do this: <?php $orig = 1; $ref = &$orig; ?> You have two variables that point to the same content. So if you unset one of them you are only erasing one of the references (take a look at the documentation above) not erasing the content itself. The content is erased when it is no more references left. If what you wanted was to delete completely the content, not the references to the content, you should do what you proposed setting to null the content. This will make that every reference acts like there wheren't set to any value, but this is only a fake because the content is the null value.
