$vals = array();
foreach($sql_result['record2'] as $key ){
    $vals[] = $key['ENO']
}
sort($vals);

or if you want to pre-sort the values you could use usort()

Untested Code, but something like the following should work....

$tmpArray = array();
foreach ($sql_result['record2'] as $key => $value) {
    array_push($tmpArray, $value['ENO']);
}

array_multisort($tmpArray, SORT_DESC);

At this point, $tmpArray will be your sorted array of values. OR, you can just do an ORDER BY clause in your SQL, in which case the result set will be ordered by the values you want.

You don't need to sort the array, you can simply append an "ORDER by ENO" to your SQL query to return an ordered result.
