[PHP4BETA] array_rand() feedback From: Andrei Zmievski (andrei <email protected>)
Date: 04/29/00

I wrote a function called array_rand() that is supposed to return a
random element from the input array. After I wrote it, I asked myself:
would it be useful to return the key for that value as well as the value
itself? What do you think?

Example (without key):

$ar = array(1, 2, 3);
$val = array_rand($ar);

Example (with key):
$ar = array("one"=>1, "two"=>2, "three"=>3);
list($key, $val) = array_rand($ar);

Let me know what you think. I also thought about adding a second
argument that specifies how many random elements to return. If that gets
added then returning keys and values for multiple arguments gets a
little trickier.
