To PDO, your db connection file will look like this,

    <?
        $servername = "localhost";
    $username = "username";  // Enter your db username
    $password = "password";  // Enter your db password
    $dbname = "myDBPDO";   // Enter your db name

    try {
    $conn = new PDO("mysql:host=$servername;dbname=myDB", $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();
    }

    ?>

Now comes your code,

<?

   if(isset($_GET['id1'])){
        $id=$_GET['id1'];
        $result=GetWordsById($id);//Here GetWordsById is a function calling store procedure
        if($result->fetchColumn()>0){

            $row=$result->fetch(PDO::FETCH_ASSOC);
        $word=$row['word'];
        $meaning=$row['meaning'];
        $synonym=$row['synonym'];
        $antonym=$row['antonym'];


        }

}

and function,

function GetWordsByID($id){
    include("conn.php");
    $result=$conn->prepare("  ");//Here sql statement 
    $result->execute();
    return $result;
}
