Alternatively, you can select a MySQL database to use after a PHP PDO object has already been created as below:

With USE STATEMENT. But remember here USE STATEMENT is mysql command

try
{
    $conn = new PDO("mysql:host=$servername;", $username, $password);
    // set the PDO error mode to exception
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $conn->exec("use databasename");
    //application logic
}
catch(PDOException $e)
{
    echo $sql . "
" . $e->getMessage();
}

$conn = null;
