check for found results in controller

How to check if there are results found with a model?

PHP Code:

$array = ['country_id' => $postData['country_id']];
$cities = $this->CitiesModel->where($array)->orderBy('id', 'asc')->findAll();
if($cities){
// OK
} else {
// No results found
} 


PHP Code:

if (isset($$cities)) {
    // ok
} else {
    // no data returned
}

Another option:

Code:

$result = $cities ?? null;

if($result){
  ... result found
}else{
  . ..result not found
}
