PHP/Mapscript, Find what Shape of layer one is each point of layer 2 in

[Ed Martin]

i have a layer of cities and a layer of counties, and right now i'm
trying to make a table in mysql of that county each city is in, the
problem is i can't figure out how should go about doing this, what i
have done so far is make an array of all the points in the cities
layer, but then after that i'm stuck as to how to determine what county
that point it is in, this is the code i have so far, and i just get
thousands of errors saying nothing found

-----code-----
$map = ms_newMapObj("map/map.map");
$cities = $map->getlayerbyname('Cities');
$counties = $map->getlayerbyname('County');
$cities->open();
$id = 0;
$query = 'SELECT id FROM cities ORDER BY id DESC';
$result= mysql_query($query);
$id_max = mysql_fetch_array($result, MYSQL_NUM);
$id_max[0]--;
//get the shape, then line, then point for each city
while ($city_shape[$id] = $cities->getshape(-1, $id)){
     if ($id >= $id_max[0]){
         break;
     }
     $id++;
}
$cities->close();
$size = sizeof($city_shape);
$dont_touch = array();
for ($i = 0; $i<$size; $i++){
     $city_line[$i] = $city_shape[$i]->line(0);
     if (!is_object($city_line[$i])){
         $dont_touch[] = $i;//for some reason 3 lines return false
instead of a point
         //so this makes an array of those so they can be skipped
     }
}
for ($i = 0; $i<$size; $i++){
     if (in_array($i, $dont_touch)){
         continue;//skip the non-objects
     }
     $city_point[$i] = $city_line[$i]->point(0);
}
for ($i = 0; $i<$size; $i++){
     if (in_array($i, $dont_touch)){
         continue;//skip the non-objects
     }
     $counties->querybypoint($city_point[$i], MS_SINGLE, 1);//this justs
gives errors
     //once i can get the id of the county i feel i will be able to dump
it to mysql
}
