[DOC] "expr1 ?: expr1" is a shortcut for: "expr1 ? expr1 : expr2" as
exists in gcc and discussed some time back. Note that this is not
an implementation ifsetor($var, default). While ifsetor would not
generate any message for non existing variables or array indices
the ternary shortcut does. Also the ternary shortcut does a boolean
evaluation rather then checking for isset(). That way ther ternary
shortcut can work on any expression while ifsetor can only work on
variables. Also to be silent one has do do: "@$expr1 ?: $expr2".
- Fixed bug #36214 (__get method works properly only when conditional operator is used).
- Fixed bug #39449 (Overloaded array properties do not work correctly).
- Fixed bug #39990 (Cannot "foreach" over overloaded properties).
# This time i added:
# ZEND_FE_RESET_VARIABLE
# ZEND_FE_RESET_REFERENCE
# and dapted parser,compiler,executor,interfaces to handle these flags
# their purpose is to be able to pass whetehr foreach is done by ref to
# the current() handler so that it can error out in case it is not capable
# to comply to the requested return signature/protocol/semantics (weyp).
- Extensions which delete global variables need to use new special function
- delete_global_variable() (I'm about to rename it) to remove them.
- Will post to internals@ or via commit messages if there's anything else.
Note that this is available for downwards compatibility only - and it doesn't
work if you use new features (namely, interfaces). Generally, people should
declare their classes before using them, but we just didn't want hell to break
loose (c)
implementation, and allows exceptions to 'fire' much earlier than before.
Instructions on how to use the new mechanism will follow on internals@
shortly...
Note - this (most probably) breaks the current implementation of
set_exception_handler()
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)
