How to access a single element of an array without knowing its key?

Question

PHP

Hello!
Let's say there is a code: How can you deduce this very "value" without resorting to "crutches" like:
$some_array[mt_rand(0, 8)] = 'value';

$some_array[mt_rand(0, 8)] = 'value';
foreach($some_array as $val)  
  echo $val;

?

Answer 1

current($arr) or end($arr)
