PHP Simple Method for Regular Matching of Provinces and Cities

In this paper, an example is given to describe the simple method of regular matching between provinces and cities by PHP. Share it for your reference, as follows:

Regular matching of provinces and cities

preg_match('/(.*?( Province | Autonomous Region | Beijing | Tianjin ))+(.*?( City | Autonomous prefecture | Region | Division | County ))+(.*?( District | County | Town | Township | Street ))/', $address, $matches);

Get an array of provinces and cities

$address = ' Nanshan District, Shenzhen City, Guangdong Province ';
preg_match('/(.*?( Province | Autonomous Region | Beijing | Tianjin ))/', $address, $matches);
if (count($matches) > 1) {
  $province = $matches[count($matches) - 2];
  $address = str_replace($province, '', $address);
}
preg_match('/(.*?( City | Autonomous prefecture | Region | Division | County ))/', $address, $matches);
if (count($matches) > 1) {
  $city = $matches[count($matches) - 2];
  $address = str_replace($city, '', $address);
}
preg_match('/(.*?( District | County | Town | Township | Street ))/', $address, $matches);
if (count($matches) > 1) {
  $area = $matches[count($matches) - 2];
  $address = str_replace($area, '', $address);
}
return [
  'province' => isset($province) ? $province : '',
  'city' => isset($city) ? $city : '',
  'area' => isset($area) ? $area : '',
];

I feel that there should be a better way. Welcome to comment and leave a message
