- use the same type (int) for zval.value.usr.len and zval.value.str.len
- use union "zstr" as char*/UChar* mixture instead of void*
- Z_UNISTR() and Z_UNILEN() no longer check for Z_TYPE()
- nuke int32_t from ZE (not finisned)
__clone() is back to not requiring any arguments, as $that is no longer
needed ($this already contains a copy of the original object, by the time
we __clone() is executed).
Calling the parent clone is done using parent::__clone()
implementation.
Using clone directly is now done using
$replica = clone $src;
Clone methods must now be declared as follows:
function __clone($that)
{
}
Clone methods in derived classes can call the __clone method of their parent
classes using parent::__clone($that)
hidden destructors.
#
# If we set the error level to E_ERROR what we must to to be correct and an
# object needs to be automatically destructed in shutdown process then the
# exit would cause memory corruption and a SEGV.
# The default behaviour is to copy all properties with all current values
# from the old object. But if __clone is overwritten then only the default
# properties are cloned with their correct default values. So we keep
# the type system intact and also allow real __clone overwriting now.
# This is somewhat discussable. I copied all properties from the old to the
# new object. But for type correctness we only need to copy the properties
# declared in the class and its parents.
#
# Also someone might want to take care about static and const members.
- $that as discussed at the PHP Conference. If there are any objections
- alternative names please let me know. The reason for changing it from
- $clone is because $clone sounds as if it's the newly cloned object and
- not the old one.
This should work as follows: if class hasn't member with given name,
__get/__set is called. If class has no method with given name, __call is called.
__get/__set are not recursive, __call can be.
