Here the name of the variable to reference is not stated explicitly; it is computed by expansion of `$(x)'. The reference `$(x)' here is nested within the outer variable reference. The previous example shows two levels of nesting, but any number of levels is possible. For example, here are three levels: x = y y = z z = u a := $($($(x)))

Reference types variables, on the other hand, don’t hold the value itself. They hold a reference that points to where the object lives in memory.

Remembering this would be an impure function in the functional paradigm, since we are changing the value of a variable by reference. $y = 10; (function() use (& $y){ $y = $y * $y; var_dump ($y); // 100})(); var_dump ($y); // 100?>
