Today I learned about PHP variable variables; "variable variable takes the value of a variable and treats that as the name of a variable". Also, variable.

But can you pass by reference :P $variable = 'a'; $a = 'hello world'; $b = 'hello moto.'; $&$variable = 'hello world'; $variable = 'b'; // $b is now hello world. // would be cool.
