seems like you've done your best to make it sound as confusing as possible,
this happens sometimes when you no longer see the wood for the trees :-)

'USERS' seems like an odd namew for the table in question.

did the phone ring whilst you we're writing that sentence?
keep reading ... it gets more php related as we go one ...

I'm not grokking that array structure much.

sidenote: I never see the point of assign the vars like that anyhow, why not just use
$result['name'] and do away with the exytra $name var?

why? I'd guess it's because you want to do a 'look-up' of the data, that
would suggest you don't want to be extracting the data on a row by row basis,
but rather grab all the data and parse it into a format you can use for
multiple look ups, here's a little class idea,maybe it offers some
inspiration/insight/relief (it untested because I can't be bothered to setup a DB):
abstract class Populations
{
static function getAll($type = null)
{
self::init();
if ($type) {
return isset(self::$data[$type]) ? self::$data[$type] : null;
}
return self::$data;
}
static function byId($id)
{
return self::get('names', intval($id));
}
static function byPlaceName($name)
{
return self::get('names', strtolower(trim($name)));
}
static function byCountryName($name)
{
return self::get('countries', strtolower(trim($name)));
}
static private function get($k, $v)
{
self::init();
if (isset(self::$data[$k][$v]))
return self::$data[$k][$v];
return null;
}
private static function init()
{
if (!isset(self::$data))
self::loadData();
}
private static function loadData()
{
self::$data = array(
'ids' => array(),
'names' => array(),
'countries' => array(),
);
// let's assume that the following query will only return
// a reasonable number of rows (i.e. not a very large number)
// let's also assume that a db connection has been setup
$res = mysql_query('SELECT id, country, name, population FROM users');
if ($res && mysql_num_rows($res)) {
while ($row = mysql_fetch_assoc($res)) {
$i = $row['id'];
$n = strtolower(trim($row['name']));
$c = strtolower(trim($row['country']));
self::$data['ids'][$i] =
self::$data['names'][$n] = $row['population'];
if (!isset(self::$data['countries'][$c]))
self::$data['countries'][$c] = 0;
self::$data['countries'][$c] += $row['population'];
}
}
}
}
you would use this class something like:
echo Population::byId(1), "\n";
echo Population::byPlaceName("Texas"), "\n";
echo Population::byCountryName("USA"), "\n";
var_dump(Population::getAll("names"));
var_dump(Population::getAll());

if you didn't then I probably have. enjoy.
