To sort an associative array according to the key of the array, you can use the ksort() function in the following manner:

<?php

$narray["IBM"]="International Business Machines";
$narray["MS"]="Microsoft";
$narray["CA"]="Computer Associated";
$narray["WHO"]="World Health Organization";
$narray["UK"]="United Kingdon";
$narray["BA"]="Something Random";

ksort($narray);

foreach($narray as $key => $value)
{
print $key . " = " . $value . "<br />";
}

?>

Similarly, you can sort an associative array according to the key, in ascending order by using the krsort() function.

You can use usort:

function my_array_sorter($a, $b)
{
    return strcmp($a['name'], $b['name']);
}

usort($my_array, 'my_array_sorter');

If you mean you are using associative arrays:

arsort($array)

asort sorts values, arsort in reverse.

ksort sorts keys, krsort in reverse.
