SYNOPSIS
       bool rsort (array  &$array, [int  $sort_flags = SORT_REGULAR])

DESCRIPTION
	This function sorts an array in reverse order (highest to lowest).

PARAMETERS
	      o $array
		- The input array.

	      o $sort_flags
		- You may modify the behavior of the sort using the optional parameter $sort_flags, for details see sort(3).

RETURN VALUES
	Returns TRUE on success or FALSE on failure.

EXAMPLES
       Example #1

	      rsort(3) example

	      <?php
	      $fruits = array("lemon", "orange", "banana", "apple");
	      rsort($fruits);
	      foreach ($fruits as $key => $val) {
		  echo "$key = $val
";
	      }
	      ?>

	      The above example will output:

	      0 = orange
	      1 = lemon
	      2 = banana
	      3 = apple

	       The fruits have been sorted in reverse alphabetical order.

NOTES
       Note

	      This  function assigns new keys to the elements in $array. It will remove any existing keys that may have been assigned, rather than
	      just reordering the keys.
