535aa63293 Add 'final' 2003-02-24 12:05:58 +00:00

e645f20d07 Allow namespaces to have a number of parts. I.e., now you can do: 
namespace foo {
	function abc() {}
}
...
namespace foo {
	functio def() {}
}

3e45b23799 add support for ::foo syntax meaning "global one" 2003-02-16 13:27:33 +00:00
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).

2814504143 Improve parser handling of 'abstract' 2003-02-11 09:48:37 +00:00

6317e26576 - Treat $this->foo inside class X as an implicit 'public $foo' if X::$foo 
is not explicitly declared
- Forbid multiple declaration of the same variable

c073b76aac - Change "is" to "instanceof" as it explains better what the operator means. 
- "is_a" was also appropriate but ugly.

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.)

e062dffe6c - Implement public/protected/private methods. 
- Prevent instantiation of classes with abstract methods.
Based in part on Marcus's patch.

227f7838d6 - Fix build (thanks Marcus) 
- Implement abstract methods, syntax:
-    abstract function foo($vars);
- I don't see any reason why modifiers such as static/public need to be
- used with abstract. PHP is weakly typed and there would be no meaning to
- this anyway. People who want a strictly typed compiled language are
- looking in the wrong place.

830c2e0df6 fix statics - make it behave like $this (fetch type "static") 
Side effect: indirect references to statics won't work.

c497868005 - Add support for static methods. Basically methods which are defined as 
- static don't have $this. That's the whole difference.

983be5c73c - ATTENTION: Finally nuke old_function and cfunction. I think it is time 
- to get rid of these BC notations. This is from the days of the move from
- PHP/FI 2 -> PHP 3

046bdeaaab - Support new classname::$class_name, e.g.: 
<?

	class foo::bar {
		public $hello = "Hello, World\n";
	}

	$name = "bar";
	$obj = new foo::$name;
	print $obj->hello;

f78fa50423 - Megapatch to try and support inheritance from sub-classes. Things might 
- be *very* buggy now so don't get too upset if that happens.
- I still need to improve some stuff but it's a good step (hopefully).

52406cb37c - Make new 'is' operator work with classes only and return false when 
- the object isn't of the said class or the value isn't an object.

bc5ea87e28 - Commit patch to support protected member variables (by Timm Friebe w/ 
- some fixes by me).
- You can't access protected variables from outside the object. If you want
- to see a protected member from your ancestors you need to declare the
- member as protected in the class you want to use it in. You can't
- redeclare a protected variable as private nor the other way around.

7b68f5108a - Nuke delete(). It was a big mistake to introduce it and I finally 
- understand why Java didn't do so.
- If you still want to control destruction of your object then either make
- sure you kill all references or create a destruction method which you
- call yourself.

a990c4da3e - Finish covering all parsed methods to check for validity in parser. 
- Change zval's refcount to zend_uint (If it doesn't slow down the Engine
- too much it should probably stay this way). If anyone has time to test
- the difference in speed between zend_ushort & zend_uint in zend.h of
- the struct _zval_struct (one line change) I'd be glad to get some
- figures.

b90d80b588 - Initial patch to support importing from class scopes (for Stig). 
- It isn't complete yet but I want to work on it from another machine. It
- shouldn't break anything else so just don't try and use it.
- The following is a teaser of something that already works:
<?php

	class MyClass
	{
		function hello()
		{
			print "Hello, World\n";
		}
		class MyClass2
		{
			function hello()
			{
				print "Hello, World in MyClass2\n";
			}
		}
	}

	import function hello, class MyClass2 from MyClass;

	MyClass2::hello();
	hello();
?>

	}

	class MyClass2 extends MyClass {

	$obj = new MyClass();

	$obj->printHello(); /* Should print */

	$obj = new MyClass2();
	print $obj->Hello; /* Shouldn't print out anything */
	$obj->printHello();
