This will sort subnets correctly:
<?php
$zones =
array('192.168.11',
'192.169.12',
'192.168.13',
'192.167.14',
'192.168.15',
'122.168.16',
'192.168.17'
);
function sort_subnets ($a, $b) {
$a_arr = explode('.', $a);
$b_arr = explode('.', $b);
foreach (range(0,3) as $i) {
if ( $a_arr[$i] < $b_arr[$i] ) {
return -1;
}
elseif ( $a_arr[$i] > $b_arr[$i] ) {
return 1;
}
}
return -1;
}
usort($zones, 'sort_subnets');
print '<pre>';
print_r($zones);
print '</pre>';
?>
