Description:
------------
Whenever a variable is refered anywhere inside a class under the form $this->varname, it is automatically created in class instances.



Reproduce code:
---------------
class A {
	function NotAConstructor(){
		if(isset($this->x)){
			//just for demo
		}
	}
}

$t=new A();
var_dump($t);

Expected result:
----------------
object(a)#1 (0) { }


Actual result:
--------------
object(a)#1 (1) { ["x"]=> NULL }

Works as expected with PHP 4, fails with PHP 5.

PHP5 knows the concepts of implicit public properties and dynamic properties.

Implicit public properties are properties that are declared by simply using them.

Dynamic properties are properties that can be 'attached' to an object while using it.

Reopen as feature request:

Shouldn't creation of implicit public properties be an E_STRICE error?

This is a bug, not feature request.
Andi: Assigned to you as reminder.. :)
 [2003-12-16 03:01 UTC] sniper@php.net 
This bug has been fixed in CVS.

In case this was a PHP problem, snapshots of the sources are packaged
every three hours; this change will be in the next snapshot. You can
grab the snapshot at http://snaps.php.net/.
 
In case this was a documentation problem, the fix will show up soon at
http://www.php.net/manual/.

In case this was a PHP.net website problem, the change will show
up on the PHP.net site and on the mirror sites in short time.
 
Thank you for the report, and for helping us make PHP better.
