Hi!
Can anyone write up a summary of the situation and the options we
have?
Sure. A number of array functions in 5.2 accept arrays, but use
HASH_OF to extract array value, which means they automatically
accept objects if the object has working get_properties handler. In
5.3, such function use new API with 'a' parameter, which accepts
only arrays proper.
The proposal is to have some new parameter - say 'a%' - which would
call HASH_OF on objects where it makes sense. The definition of
"makes sense" is not clear yet, since, for example, sort() on some
objects may make sense - if the object's get_properties returns real
storage - or may not, if that handler returns the mere copy of the
real data. We might use some interface as a marker - like
ArrayAccess - though I'm not sure if it will work in all
circumstances.
So what if we for now stick with the BC fix?
However maybe for PHP 6.0 we should make a real effort to figure out
how objects are supposed to be handled in our PHP type juggeling world.
