Ummm, I'm pretty sure it's a variable variable - basically a way to have a dynamically named variable. Here they are in the manual http://php.net/manual/en/language.va...s.variable.php
Cool though they may be, I never use variable variables, because they're a bit confusing - they save a few lines of code but lose maintainability and readability IMHO.
