You need to detect the first blank space between the town in a foreach loop or similar loop and the $suggestions array contains only the hometowns without its same neighbors.

Example:

foreach ($suggestion_cities as $key => $city) {
    if(preg_match('/\s/',$city->city)) {
        continue;
    }
    $suggestions[] = array(
        'value' => $city->city,
        'value_type' => 'city'
    );
}
