Hello.
1.
I recently discovered that it´s possible to return a reference to a static
variable. Is this supposed to work, will it stay that way in future
versions?
2.
Static variables are "shared" between multiple instances of the same object.
Is this
intended behaviour?
3.
Could someone give a rough estimation of how big the performance loss is
when using classes instead of plain functions in PHP?
Regards
Marten.
