2e6d655efd MFH: - Saved opcode when unary +/- is applied to IS_CONST op (e.g. for negative numbers) 
- Made '+' in static_scalar context behave as '-' by calling add_function()

478acfd8b4 . Added support for using static HEREDOCs to initialize static variables and class members or constants. (Matt) 
. Improved syntax highlighting and consistency for variables in double-quoted strings and literal text in HEREDOCs and backticks. (Matt)
. Optimized interpolated strings to use one less opcode. (Matt)

45f6b4ce2f - MFH Improved version of ternary shortcut (Marcus) 2007-11-21 09:41:35 +00:00
Johannes Schlüter
4a8ed7ab68 - MFH ?: operator (Marcus) 
[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".

# This time i added:

# and dapted parser,compiler,executor,interfaces to handle these flags

# 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).

c5d842279c Reinstate early-binding for classes. 
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)

9e60cb553f Rewrote exception support. Fixes a few limitations and bugs in the old 
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()

8e30d96ad8 Redesign the clone() feature to fix some fundamental flaws in the previous 
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)

530789987f - Head up! I'm reverting the patch which allows for expressions in constant 
- declerations. Allowing the access of other constants in this code is
- flawed. We are reverting back to PHP 4's static scalars.
- Don't worry if you get the following msg when compiling:
- "zend_language_parser.y contains 3 useless nonterminals and 22 useless rules"

f8bbafd604 ntroduce infrastructure for supplying information about arguments, 
including:

- Whether or not to pass by ref (replaces the old arg_types, with arg_info)
- Argument name (for future use, maybe introspection)
- Class/Interface name (for type hints)
- If a class/interface name is available, whether to allow a null instance

Both user and builtin functions share the same data structures.

To declare a builtin function that expects its first arg to be an instance
of class 'Person', its second argument as a regular arg, and its third by
reference, use:

ZEND_BEGIN_ARG_INFO(my_func_arg_info, 0)
    ZEND_ARG_OBJ_INFO(0, someone, Person, 1)
    ZEND_ARG_PASS_INFO(0)
    ZEND_ARG_PASS_INFO(1)
ZEND_END_ARG_INFO();

and use my_func_arg_info as the arg_info parameter to the ZEND_FE() family
of macros.

The first arg to each ZEND_ARG_*() macro is whether or not to pass by ref.

The boolean arg to ZEND_BEGIN_ARG_INFO() tells the engine whether to treat
the arguments for which there's no explicit information as pass by reference
or not.
The boolean argument to ZEND_ARG_OBJ_INFO() (4th arg) is whether or not to allownull values.

0191ba5de1 allow expressions within constants, so the following is possible 
class foo {

	const b = 1<<1;

}

this makes const a compile-time expression.  all other operators are
unaffected.

Stanislav Malyshev
a4c3b2ce80 Namespace patch. Big changes: 
1. Nested classes are gone.
2. New syntax for namespaces:
namespace foo {
	class X { ... }
	function bar { ... }
	var x = 1;
	const ZZ = 2;
}
3. Namespaced symbol access: $x = new foo::X; - etc.
For now, namespaces are case insensitive, just like classes.
Also, there can be no global class and namespace with the same name
(to avoid ambiguities in :: resolution).

32b100e6cb - Allow variables to have both 'static' modifier and an access level. 
NOTE:  This only works at the syntax level right now (parser).  It
         doesn't actually work as of yet - all statics are considered
         public for now
- Prevent users from putting more restrictions on methods in derived classes
  (i.e., you cannot make a public method private in a derived class, etc.)

- Implement abstract methods, syntax:
