Description:
------------
Apache hangs when callback parameters are defined in an array (obj& obj, string methodName) form.

I suggest the documentation type hints are changed from
xml_set_*_handler ( resource, callback, ... )

to
xml_set_*_handler ( resource, string ...)

since the an array ( ... ) notation for callbacks should be correct according to http://nl.php.net/manual/en/language.pseudo-types.php

Note that it does the parsing until some point at the end of the XML document. I can't quite reproduce where exactly it hangs, but i think its the cleaning up part of the parser when the parsing is done (the $final of xml_parse must be true to reproduce this)

or you could fix the bug, of course :P



Reproduce code:
---------------
xml_set_element_handler ( 
   $this->parserResource, 
   array ( &$this, 'startElementHandler' ),
   array ( &$this, 'endElementHandler' )
);


Expected result:
----------------
don't hang apache ;)

Actual result:
--------------
hangs apache, (99% cpu), probably an endless loop?
