    try {
        $conn = new PDO("mysql:host=$servername;dbname=lifeands_phdb_150522", $username, $password);
        // set the PDO error mode to exception
        $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
        //echo "Connected successfully";
        }
    catch(PDOException $e)

to fetch from the table "loan_calculator" of "lifeands_phdb_150522" DB. select the DB and write the query to fetch data from table

$servername = "localhost";
$username = "root";
$password = "";

try {
    $conn = new PDO("mysql:host=$servername;dbname=lifeands_phdb_150522", $username, $password);
    // set the PDO error mode to exception
    $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
    //echo "Connected successfully";
} catch(PDOException $e) {
    echo "Connection failed: " . $e->getMessage();

//to query table   
$sql = 'SELECT *  FROM loan_calculator'; 
$res = $conn->query($sql, PDO::FETCH_ASSOC);

You can simply try this

    if (!$link = mysql_connect('mysql_host', 'mysql_user', 'mysql_password')) {
      echo 'Could not connect to mysql';
      exit;
    }

   if (!mysql_select_db('lifeands_phdb_150522', $link)) {
      echo 'Could not select database';
      exit;
   }

   $sql    = 'SELECT *  FROM loan_calculator';
   $result = mysql_query($sql, $link);
