New Comment:
I have fixed this now in CVS. But the docs should mention
that the pointer is reset by array_pop/array_shift.

Clarification: In PHP 4.2.3, the current array position
was reset after array_pop() and array_shift().

[EMAIL PROTECTED]: I reverted my changes, not my fault. :-p
But there is indeed some bug in this, since array_pop()
should not affect the current key.

Array related.
One of these commits broke it.

Reset index when doing array_pop()
------------------------------------------------------------------------
[2003-02-01 13:42:12] [EMAIL PROTECTED]
<?
$a = array("a", "b", "c");
each($a);
array_pop($a);
var_dump(each($a));
?>
This prints "bool(false)" in 4.3.0 (current element pointer points
somewhere out of the array) and var_dump($a[0]) in 4.2.3 (array is
reset after array_pop).
I had to add many additional reset()'s after installing 4.3.0.
How array_pop() (and may be others) affects current element pointer is
not documented, so this behavior is not a bug. The only purpose of
writing all this is that I want to know how array_pop() will work in
future PHP releases.
