Greetings, I'm relatively new-comer to these forums and have a Q to the mods. Just wondering what's the policy regarding the long running threads where they tend to go say over 30 posts and they become "troubleshooting" threads rather than being "educational" and/or "hinting" threads? ...

prev - Rewind the internal array pointer

SYNOPSIS
mixed prev (array &$array) DESCRIPTION
Rewind the internal array pointer. prev(3) behaves just like next(3), except it rewinds the internal array pointer one place instead of advancing it. PARAMETERS
o $array - The input array. RETURN VALUES
Returns the array value in the previous place that's pointed to by the internal array pointer, or FALSE if there are no more elements. EXAMPLES
Example #1 Example use of prev(3) and friends <?php $transport = array('foot', 'bike', 'car', 'plane'); $mode = current($transport); // $mode = 'foot'; $mode = next($transport); // $mode = 'bike'; $mode = next($transport); // $mode = 'car'; $mode = prev($transport); // $mode = 'bike'; $mode = end($transport); // $mode = 'plane'; ?> NOTES
Warning This function may return Boolean FALSE, but may also return a non-Boolean value which evaluates to FALSE. Please read the section on Booleans for more information. Use the === operator for testing the return value of this function. Note You won't be able to distinguish the beginning of an array from a boolean FALSE element. To properly traverse an array which may contain FALSE elements, see the each(3) function. SEE ALSO
current(3), end(3), next(3), reset(3), each(3). PHP Documentation Group PREV(3)
