What are you expecting? Check out the documentation for each() at 
http://www.php.net/manual/en/function.each.php

At this point $arr3 should look like this (I think, but try 
print_r($arr3) to be sure):

{
0 => 0,
1 => array (
        0 => array (
                0 => 1,
                1 => 10
                )
        ),
key => 0,
value => array (
        0 => array (
                0 => 1,
                1 => 10
                )
        )
}

How about foreach()?
