add key pair value in array in foreach loop PHP

Question

I want to make an key pair array in foreach loop in php. In my foreach loop i have city name and user name. I want to add all users for same city in array.

Ex [{city=>'pune',users=>("a","b","c","d")},{'city=>nk',users=>("e","b","c","f")}] or any other array format.

foreach ($studsInfo as $value) {
    $studId = "".$value['_id'];
    $indDetail = $industryM->getAllIndustries($studId);
    $indusArray['industry'] = iterator_to_array($indDetail);
    $city = $value['city'];
    $name = $value['firstname'];
}

How could I add all name in array for same city.

Thankx in advance, Any suggestion and editing are welcome

You can use the city as the key users from the city as value.

$arr = [];
foreach ($studsInfo as $value) {
    $studId = "".$value['_id'];
    $indDetail = $industryM->getAllIndustries($studId);
    $indusArray['industry'] = iterator_to_array($indDetail);
    //$city = $value['city'];
    //$name = $value['firstname'];
    $arr[$value['city'][] = $value['firstname'];
}
foreach($arr as $k => $v) {
    $result[] = array('city' => $k, 'users' => $v);
}
