Sorting an array by keys can be done by using the ksort() function. It will re-order all pairs of keys and values based on the alphanumeric order of the keys. Here is a PHP script on how to use ksort():

<?php
$mixed = array();
$mixed["Zero"] = "PHP";
$mixed[1] = "Perl";
$mixed["Two"] = "Java";
$mixed["3"] = "C+";
$mixed[""] = "Basic";
$mixed[] = "Pascal";
$mixed[] = "FORTRAN";
ksort($mixed);
print("Sorted by keys:\n");
print_r($mixed);
?>

This script will print:

Sorted by keys:
Array
(
    [] => Basic
    [Two] => Java
    [Zero] => PHP
    [1] => Perl
    [3] => C+
    [4] => Pascal
    [5] => FORTRAN
)
