Cast to unset

  1. Default Cast to unset

    In the PHP grammar I encountered the feature of casting to unset, e.g.
    (unset)$a. I did not manage to find any specific documentation on this,
    only people wandering what it might do
    (http://blog.thinkphp.de/archives/33-Casted-fun..html).

    So what exactly does cast to unset do?

    Thanks,
    Robert

    If it ain't a Documented Feature, don't use it. :-)

    I presume it's the same as unset($a); though.
