   (PHP 3>= 3.0.8, PHP 4 )
   shuffle -- Shuffle an array

Description

   void shuffle ( array array)

   This function shuffles (randomizes the order of the elements in) an
   array. You must use srand() to seed this function.

   Example 1. shuffle() example
   <?php
   $numbers = range(1, 20);
   srand((float)microtime() * 1000000);
   shuffle($numbers);
   while (list(, $number) = each($numbers)) {
       echo "$number ";
   }
   ?>

     Note: As of PHP 4.2.0, there is no need to seed the random number
     generator with srand() or mt_srand() as this is now done
     automatically.
