If you've already got the answers stored in $_POST by qId, and you're using [] in your input names, as Aret suggests, you could do something like:

// creates an object, $stmt, which will do an insert whenever $stmt->execute()
// is called
$stmt = $conn->prepare('INSERT INTO Answer (qId, answer) VALUES (:qId, :answer)');

$sql="select qId from Answer"; 
$result = mysql_query($sql) or die(mysql_error());

// loop over all question ids
while( $row = mysql_fetch_assoc( $result ) ) {

  $qId = $row['qId'];

  // loop over all the answers for one question
  foreach ($_POST[$qId] as $answer) {

    // this runs the sql from the first line with :qId set to $qId, 
    // and :answer set to $answer
    $stmt->execute(array(':qId' => $qId, ':answer' => $answer));

  }
