Weak references is an OOP concept. Scalar data types and arrays are not OOP-related so I don't think that would make sense. Variable references is not the same as object references. A variable reference is simply a variable that is connected with another variable (if you set one it will change the other). If two variables have the same object reference they are not connected, if you set one variable the other is still set to the initial object reference.
Also, arays and strings have special memory handling - they use lazy copying so it's opaque if two equal arrays/strings refer to the same region of memory. It's unclear what construction/destruction even mean in that sense. An array might actually have been "constructed" by the compiler. A reference to an object instance is a "pointer" but a reference to a variable is not. http://us.php.net/manual/en/language.references.arent.php I hope that illustrates the difference. Do you have any special use case in mind? ~Hannes On 18 July 2011 20:12, Adam Harvey <ahar...@php.net> wrote: > > This may just be Monday morning fuzziness, or I've just missed something in > the RFC, but is there a reason weak references would be limited solely to > objects, rather than any variable that can be dealt with by-reference? > > Thanks, > > Adam >
