How to cut an array?

[summer]

Is there a quick way for cutting off data from an array? Let's say I have an array with 200 keys but I need only 10 of them.

I guess I could generate a new array as an alternative but maybe there is a faster way of doing it?

$new_array = array_slice ($array, 0, 10);
