[PHP] Cast to unset

2007-02-27 Thread Robert Enyedi
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
