How to sort associative array

I want to sort the key of the following array. I use ksort(), but i don't know how to use it. Any idea?

<?php
        $a = array(
                'kuy' => 'kuy',
                'apple' => 'apple',
                'thida' => 'thida',
                'vanna' => 'vanna',
                'ravy' => 'ravy'
              );

        $b = ksort($a);
        echo "<pre>";
        print_r($b);
        echo "</pre>";
    ?>

Maybe ksort is not the right function. It depends on what you want to sort. Here is a list of all sort functions. To learn how to use a function, have a look at its documentation, e.g. php.net/manual/en/function.ksort.php

so what does print_r($b) show you? Have you read this php.net/manual/en/function.ksort.php? It is hard to be any clearer really.

ksort() sorts the array itself and does not create a sorted copy

$a = array(
  'kuy'   => 'kuy',
  'apple' => 'apple',
  'thida' => 'thida',
  'vanna' => 'vanna',
  'ravy'  => 'ravy'
);

ksort($a);
echo "<pre>";
print_r($a);
echo "</pre>";
