尝试以下，它应该为你工作。

public function selectLocations($POST) 
    { 
     $location = array(); 
     $SELECT_CITY = "SELECT DISTINCT city FROM listings WHERE Matrix_Unique_ID > 0 LIMIT 0,5"; 
     $cityresult = $this->conn->query($SELECT_CITY); 
     while($row = $cityresult->fetch_assoc()) 
     { 
      $location['city'][] = $row['city']; 
     } 

     $SELECT_STATE = "SELECT DISTINCT state_or_province FROM listings WHERE Matrix_Unique_ID > 0"; 
     $stateresult = $this->conn->query($SELECT_STATE); 

     while($row1 = $stateresult->fetch_assoc()) 
     { 
      $location['state'][] = $row1['state_or_province']; 
     } 

     return $location; 
    }
