Hello,
I have a case where an object has a few variables, a couple of which
are objects which hold references back to this object.
So very simply something like
class A {
var B
}
class B {
var A
}
When doing something like so
$obj = new A(); in a loop the object's never released from memory
because of the internal references it holds. __destruct is not called
until the end of script execution etc. Now normally in a web request
situation this isn't a big deal. However I'm using it in a batch and
loop over 22 000 records. Since re-assigning the single object I use
isn't freeing any memory it consumes quite a bit. I have gotten around
it by creating a special function in the object to manually release the
recursive references. However it would be nice if there were some sort
of 'magic' function that could be called on an object so that it knows
it is being deleted, sort of like a __preDestruct or something like
that... Is that a bad idea? Or I guess better able to handle recursive
references in objects would be the other way to solve it I guess.
Any feedback is welcome.
