    (PHP 3>= 3.0.13, PHP 4 , PHP 5)
krsort -- Sort an array by key in reverse order
Description
bool 
krsort ( array &array [, int sort_flags] )
     Sorts an array by key in reverse order, maintaining key to data
     correlations. This is useful mainly for associative arrays.
    
     Returns TRUE on success or FALSE on failure.
    
     
| Example 1. krsort() example | 
<?php$fruits = array("d"=>"lemon", "a"=>"orange", "b"=>"banana", "c"=>"apple");
 krsort($fruits);
 reset($fruits);
 while (list($key, $val) = each($fruits)) {
 echo "$key = $val\n";
 }
 ?>
 | 
 The above example will output: | d = lemon
c = apple
b = banana
a = orange |

     parameter sort_flags, for details
