you simply can?t do it that way, please read the manual on foreach() etc. and that additional "&" in 
> $array = array(&$array2);
has absolutely no effect here, at least not what you expect it to do (please also read "references explained")

> print next(current($array))."<br>"; // returns 1, correct > but the internal
> pointer is only moved in the copy current() returned

sure, current($array) returns a copy and thus all results you?ve mentioned are fine

1. yes, i have read the manual on references explained.

2. ok, array(&$array2) might not work but i can't see why.

what if we make it like this? shouldn't this work
or it should work like this if current(), reset(), prev() and next() were modified to return references instead.

<?PHP
$array = array(array(0,1,2));

print current(current($array))."<br>"; // returns 0

print "<b>Try 1!</b><br>";
print next(current($array))."<br>"; // returns 1, correct but the internal pointer is only moved in the copy current() returned
print current(current($array))."<br>"; // returns 0, wrong, should be 1
print current($array[0])."<br>"; //returns 0, wrong, should be 1

print "<b>Try 2!</b><br>";
print next($array[0])."<br>";
print current(current($array))."<br>"; // returns 0, wrong, should be 1
print current($array[0])."<br>"; // returns 1, yes, correct! but the code above still didn't work!
?>

I really think that this behaviour should be changed, i need it for a project i'm working with.

There's no & operation in PHP. Thus, you cannot use it in expressions, including array(). There's =& operator and &$var syntax for passing variables by reference.

Also, if language doesn't do what you need for a particular project, it's usually not good enough reason to change the language. Anyway, I move it to feature requests.

This file is rather old (9 years? wow!)...

What i can't do in PHP 5.2 currently is:

$a = array(2,5,8);
$e =& end($a);

I have to do this instead:

$a = array(2,5,8);
end($a);
$e =& $a[key($a)]; /* Overhead with an extra function call, and a key lookup */

It would be nice if current(), reset(), end(), next() and prev() would return references at least...

This is how it works. No way we should even consider changing it.
