[305] => 305
[306] => 306
[307] => 307
[308] => 308

Quickest way I can think of would be to do something like

$tmp = array();

foreach($old_array as $key => $value)
{
$tmp[$value] = $key;
}

But knowing PHP there is probably some array_reverse_keys() function.

$array = array_values($array);

Or, if you don't want to preserve the original array AND you want the
data sorted ...

sort($array);

There are two ways I see to do it. You can iterate the array and create
a copy, assigning elements dynamic values:

$new_array = array();
foreach($array as $a)
{
$new_array[] = $a;
}

or use a sorting function on it that doesn't preserve the keys (as in
your example all the values in the array were in numerical order.

$new_array = sort($array);

Having said that, if the key isn't important, and it doesn't seem to be
if you want to change it, then why not use a foreach and leave the key
as it is?

The fastest way is going to be array_values():
