It probably does, but it is quite subtle. I was expecting the above to work since it does in C -- although in C&variable is an address which can be used in an expression ... the PHP '&' operator is different, in spite of apparent similarities.
Actually, in PHP standalone & doesn't even make any sense. PHP has certain operations - assignment by reference (bind two names to one variable) and passing by reference (which is the same thing but cross-scope) and returning by reference (which again is the same thing but in opposite direction). But unlike C there's no operation "taking reference" because while C has pointers PHP doesn't have anything like that.
