Fixed but #29437 (Possible crash inside array_walk_recursive()).

proto fix
(thanks to dave%php.net for spotting)

make behavior a bit field

add array_:
intersect_key()
intersect_ukey()
diff_key()
diff_ukey()
The first two by a patch of Cristiano Duarte. The second two were
implemented in almost the same way except

The same kind of overflow appeared in array_splice(), substr() and
substr_replace()

array_*diff() and array_*intersect() not clearing the fci cache before work.
FCI call cache was introduced in HEAD. All functions that perform sorting
of arrays clear the fci cache before work. array_*diff() and\ array_*intersect()
were somehow missed to be updated.

fixing bug 29038:
EXTR_PREFIX_SAME is prevented from creating a new variable when the key
is a empty string. EXTR_PREFIX_ALL is also prevented from doing that,
but works for numbers.

Fixed bug #29008 (array_combine() does not handle non-numeric/string keys).

Fixed bug #29049 (array sorting via user function/method does not validate
it).

Update for count_elements handler for overloaded objects.

MFB: Revert patch for bug #27782.

Fixed bug #27782 (Wrong behaviour of next(), prev() and each()).

this should not belong to HEAD

Added third parameter (optional) to array_keys for strictness. It behaves
like the "strict" parameter of in_array().
#Closing feature request #24258

HEAD is now bundled only with ZE2

New array functions for doing intersection of arrays that are complementary
to array_*diff* family of functions. Namely array_uintersect(), array_uintersect_assoc(),
array_intersect_uassoc()

New array functions for doing intersection of arrays that are complementary
to array_*diff* family of functions. Namely array_uintersect(), array_uintersect_assoc(),
array_intersect_uassoc() and array_uintersect_uassoc(). Test case is also included.

Fixed clobbering of the source array, when merging complex
multi-dimensional arrays. Bug reported by Lukas Smith.

Fixed bug #25708 (extract($GLOBALS, EXTR_REFS) mangles $GLOBALS)

smash a segmentation fault

Memory leak fixed (no need of MFH since this is code specific to PHP5)

signed/unsigned compiler warning fixes

Fixed typo.

4 new functions :

4 new functions :
array_udiff()
array_udiff_assoc()
array_diff_uassoc()
array_udiff_uassoc()
They work like array_diff() or array_diff_assoc() but callback function(s)
can be used to perform the comparisons. For example array_udiff_uassoc()
expects 2 callbacks are last 2 parameters one is used to compare the values
of the entries in the arrays the second to compare the keys.
Class methods are also valid callbacks. Even when the data that should be
used in the comparison is private or protected then a static method of a
class should be used (this behaviour can be seen in the regression test -
007.phpt).

improve the fix for #25494. If more then one bad parameter is passed
an warning for all will be emitted.
