Пример 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().
