But you could make a more usefull function:

public static function getItemAt($collection,$index)
{
if ($index >= 0 && $index < count($collection))
{
$i = 0;

foreach ($collection AS $item)
{
if ($i++ == $index)
{
return $item;
}
}
}

return null;
}

reset() followed by each() or key() should give you the first key/value

drawback: internal pointer gets lost using reset()

This will return the first key name, eg $keyname = key($array);

You can then use next() and prev() to get keys that follow.

So if i quickly wanted the 3rd key id do this:

next($array);
next($array);
next($array);
$keyname = key($array);

The current() function is best used on
