[PHP] reset array keys

[Sic]

I can't find anything on this- maybe because there isn't anything, but I figured someone would know:

I have an array with keys that have gaps in -

key[0]
key[2]
key[4]
key[5]

is there any way for me to reset the keys so that they stay in the same order?

key[0]
key[1] //was key[2]
key[2] //was key[4]
key[3] //was key[5]

I thought there was a sort function that didn't preserve keys, but the one that sorts by key preserves them with no option not to. if I have to, I'll write a function, but there's no point if I don't have to!

thanks

$array = array_values($array);
