As far as I can tell, the concept is that you can define a variable (call it, for the sake of example, $foo), and assign it a value (say, the string "bar"). You can then refer to $$foo, which will tell PHP to access the variable with the same name as the string in $foo, in this case $bar.
As far as I can tell, it's simply a variant on pointers in a language such as C.
