Bad code!

You have always to check if array keys exists before accessing it!
There is no warranty that key 2 exists. Never...
Otherwise you become a error when accessing invalid keys.

$tmp = array_keys($input);
if (sizeof($tmp) >= 3)
echo $tmp[0], $tmp[2];
else
// do alternating things


So long, Ulf
