You seem to have three different ideas/questions... let me attempt to answer
them:

let's take a multidimensional array $x
$x = array(
"somevar",
array(
"otherval",
"evenmore"
)
);
echo $x[0]; should print 'somevar'
echo $x[1]; should print 'Array'
echo $x[1][0]; should print 'otherval'
echo $x[1][1]; should print 'evenmore'
>

if you want to concat all the key's of an array with a loop you could do:
reset($x); //just to make sure we are at the first key
while(list($key,$val) = each($x)){
$my_keys .= $key
}
echo $my_keys;
should result in: (using $x from my code above)
1 (I think it might even come out as 01 -- but probally 1 since it will be
treated as a int maybe =) )
