Bug description:Trait method copying misindentifies serialization callbacks
Description:
------------
_ADD_MAGIC_METHOD in zend_compile.c identifies "serialize_func" and
"unserialize_func" as magic methods and copies them to ce->serialize_func
and ce->unserialize_func.
The correct names are "serialize" and "unserialize". These names could be
changed, or, better yet, those two lines should be deleted because the
methods serialize and unserialize are only relevant if the class implements
Serializable (or, more precisely, if ce->serialize and ce->unserialize are
zend_user_serialize and zend_user_unserialize, respectively, and in any
case ce->serialize_func and ce->unserialize_func work only as a lazy cache.
Test script:
---------------
<?php
trait A {
function serialize_func() { return "serialize_func"; }
function serialize() { return "serialize"; }
function unserialize($foo) {}
}
class B implements Serializable { use A; }
echo serialize(new B);
Expected result:
----------------
C:1:"B":9:{serialize}
Actual result:
--------------
C:1:"B":14:{serialize_func}
