It's not probably a bug report but a suggestion.
Guys please could you make built-in function array_merge_clobber that WOULDN'T append duplicate key/values like array_merge_recursive does?

There's an example of such function in the php manual, in the array_merge_recursive section:

function array_merge_clobber($a1,$a2) {
if(!is_array($a1) || !is_array($a2)) return false;
$newarray = $a1;
foreach ($a2 as $key => $val) {
        if (is_array($val) && is_array($newarray[$key])) {
$newarray[$key] = array_merge_clobber($newarray[$key],$val);
} else {
$newarray[$key] = $val;
}
}
return $newarray;
}

Our application heavily depends on this function and it takes about 40% of overall script execution(very large and nested arrays)! I think many developers would agree to have this function interbally implemented.

Maybe it's not the right place...but i have no idea where else i could ask about it...

If I understand you correctly, the `+` operator can be used:

$array1 = array(0 => 'zero_a', 2 => 'two_a', 3 => 'three_a');
$array2 = array(1 => 'one_b', 3 => 'three_b', 4 => 'four_b');
$result = $array1 + $array2;
var_dump($result);
