    (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);
 foreach ($fruits as $key => $val) {
 echo "$key = $val\n";
 }
 ?>
 | 
 The above example will output: | d = lemon
c = apple
b = banana
a = orange |
