Some confusion regarding object creation in static function

[akhileshbc]

Hi guys

I have been going through some piece of code and got confused at a certain point. The below is a piece of code:

class DataManager
{
  private static function _connect()
  {
    return new PDO('mysql:host=localhost;dbname=sample', 'root','');
  }

  public static function fetch_users()
  {
    $db = self::_connect();

    $st = $db->query("SELECT * FROM users");
    //....
  }
  
  public static function func2()
  {
    $db = self::_connect();

    $st = $db->query("SELECT * FROM users");
    //....
  }

  public static function func2()
  {
    $db = self::_connect();

    $st = $db->query("SELECT * FROM users");
    //....
  }
  
  //and so on..
} 

Isn't that a bad practice ? I mean, each time when a member function is executed, the connect() function is called which will return a NEW PDO object. So, new PDO objects are created each time.

Am I correct ?

Thanks
