Bug description: Returning element value from array_rand()
Description:
------------
With array_rand() as it is now, it only returns the key of the element(s)
it picks randomly from the array. The problem with this is that much/most
of the time all the programmer wants is to get a random value from that
array - not the key.
At present you then have to do code such as
$arrayName[array_rand($arrayName)] or a foreach loop when getting multiple
random elements. Whilst of limited importance, this could quite be
implemented via the addition of a boolean parameter on the end of
array_rand without too much trouble.
Reproduce code:
---------------
<?php
$array = array('a', 'b', 'c');
$values = array_rand($array, 2, TRUE); // return the value if TRUE, the
key if FALSE (FALSE the default in order to mirror current functionality)
?>
Would be desired to get 2 random values from $array, as opposed having to
do:
<?php
$array = array('a', 'b', 'c');
$values = array_rand($array, 2);
foreach($values as &$value) {
$value = $array[$value];
}
?>
Expected result:
----------------
2 Random values from $array.
