                                     ksort

   (PHP 3, PHP 4 )
   ksort -- Sort an array by key

Description

   int ksort ( array array [, int sort_flags])

   Sorts an array by key, maintaining key to data correlations. This is
   useful mainly for associative arrays.

   Example 1. ksort() example
   <?php
   $fruits = array("d"=>"lemon", "a"=>"orange", "b"=>"banana",
   "c"=>"apple");
   ksort($fruits);
   reset($fruits);
   while (list($key, $val) = each($fruits)) {
       echo "$key = $val\n";
   }
   ?>

   This example would display:
a = orange
b = banana
c = apple
d = lemon

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

   See also asort(), arsort(), krsort(), uksort(), sort(), natsort(), and
   rsort().

     Note: The second parameter was added in PHP 4.
