PDO Close Database Connection

We can connect database with PDO by

try
{
     $con = new PDO("mysql:host=$hostname;dbname=mysql", $username, $password);
     print 'Connection Successful';
}
catch(PDOException $e)
{
     print $e->getMessage();
}

/* I used try catch for Exception Handling */

We can close the database connection of PDO by simply


$con = null;




By the simple assignment of null value to database connection object we can close connection.
