When picking only one entry, <function>array_rand</function> returns
the key for a random entry. Otherwise, an array of keys for the random
entries is returned. This is done so that random keys can be picked
from the array as well as random values. Trying to pick more elements
from the array as well as random values. If multiple keys are returned,
they will be returned in the order they were present in the original array.
Trying to pick more elements
than there are in the array will result in an
<constant>E_WARNING</constant> level error, and NULL will be returned.
