Hi,

The array_merge() fix introduced into beta2 broke my scripts, 'cause they
relied upon array_merge() to return something even if some of the passed
parameters were undef.

I used to merge values into my arrays that way, even if it was unclear
wether there was previously data in it:

$my_array = array_merge(
   $my_array,
   array(
      "fill_up" => "if_unset",
      "this" => "too",
   )
);

Which now doesn't work any longer. - this requires some code bloat to
work around now (introducing a user-level array_merge).

I don't believe the current ext/standard/array.c:php_array_merge_wrapper
addresses the problem described in #25494, it now just fails and sends
eventual paramaters of PHP:ewiki_merge() to hell, making it incompatible
to previous versions (PHP4,beta1).

Why wasn't just a warning message sufficient?!

If you guys really like to change the way that PHP function was used, then
you could replace E_WARNING with E_ERROR inside the array.c on line 2222 -
this would be less bogus than a _warning_ message that silently kills
data.
